Abstract ：
The impregnation and ion exchange methods were employed to prepare the Ni-modified clinoptilolites (CPs). Their physicochemical properties and structural features were evaluated by various characterizations, such as XRD patterns, SEM and TEM images, Raman and FT-IR spectra, XPS and H 2 -TPR, N 2 sorption isotherms, and TG analysis. The results demonstrated that the loaded Ni nanoparticles were highly dispersed on the lamellar surfaces of the synthesized CPs. Meanwhile, their CH 4 and CO 2 dry reforming reactions (DRM) at 500 -900 degrees C were conducted utilizing Ni species as active sites. The results demonstrated that the Ni-loaded CPs exhibited greater catalytic activity than the Ni-exchanged CPs, besides that, the Ni-loaded CPs demonstrated the highest catalytic stability at 700 degrees C. However, the carbon deposition of the Ni-loaded CPs seemed more difficult to eliminate than that of the Ni-exchanged CPs in the DRM durations. These results elucidate the excellent performances of the developed Ni-modified CPs for designing more stable and efficient Ni-based DRM catalysts.

Abstract ：
The purification and separation of CO2, CH4, and N-2 from biogas, flue gas, and coalbed gas for carbon capture and storage are main technology in mitigating the greenhouse effect. The Mg-MOF-74@clinoptilolite (Mg-MOF-74@CP) composites are successfully synthesized through an interfacial growth of Mg-MOF-74 onto the surfaces of the synthesized CP for adsorption and separation of CO2, CH4, and N-2. The structural characteristics of the resultant composites are systematically characterized by various characterizations. In particular, small-angle X-ray scattering (SAXS) patterns are used to elucidate the fractal structural evolutions of the parent CP, Mg-MOF-74, and Mg-MOF-74@CP. Meanwhile, the single-component adsorption isotherms for CO2, CH4, and N-2 are demonstrated. The breakthrough measurements on CO2/CH4 and cycling tests on CO2 are conducted. The results elucidate that the CO2 equilibrium capacity of Mg-MOF-74@CP is higher than that of parent CP, displaying a high affinity toward CO2, the longer breakthrough time and enhancement of CO2 uptake exhibit a better separation performance. The cycling tests on CO2 reveal that the Mg-MOF-74@CP could be used repetitively, promoting its practical application in an energy-saving and economical way. Additionally, the adsorption isotherms and adsorption sites of the prepared Mg-MOF-74@CP are simulated using the Grand Canonical Monte Carlo (GCMC) method, elucidating the mechanism of the gas separation performance of Mg-MOF-74@CP.

Abstract ：
The present work evaluated the removal performances of Ni2+, Cd2+, Sr2+, Mn2+, and Fe3+ from an aqueous solution using a comparison between synthetic clinoptilolite (SCP) and natural CP (NCP). Unlike previous demonstrations that treated each metal ion individually, these five metal ions and the used adsorbents were combined in a single treatment and explored via various characterizations, such as XRD patterns, SEM images, N2 sorption isotherms, ICP, and AAS analysis. The results revealed that the capacities of SCP at pH 3.0-8.0 and 25-75 degrees C were nearly 20 times higher than those of NCP, showing 2000, 1720, 1875, 1510, and 22 mg g- 1, for Ni2+, Fe3+, Cd2+, Mn2+, and Sr2, respectively. The reason is mostly attributed to its purity and perfect crystal lattice. The kinetic behaviors in both cases indicated that the pseudo-2nd-order model provided a better description. Their adsorption behaviors exhibited a better fit with the Freundlich models on the removal of Ni2+, Cd2+, and Mn2+, the Langmuir equation on the removal of Fe3+, and both Freundlich and Langmuir on the removal of Sr2+, respectively. The thermodynamic findings indicated that the SCP was used to be faster, more spontaneous, and had a better favorable adsorption performance than the NCP. Additionally, five times recyclability and different stability tests further supported the dominant adsorbent nature of using SCP as an adsorbent.

Abstract ：
Developing effective intelligent nanocarriers is highly desirable for fluorescence imaging and therapeutic applications but remains challenging. Using a vinyl-grafted BMMs (bimodal mesoporous SiO2 materials) as a core and PAN ((2-aminoethyl)-6-(dimethylamino)-1H-benzo[de]isoquinoline-1,3(2H)-dione))-dispersed dual pH/thermal-sensitive poly(N-isopropylacrylamide-co-acrylic acid) as a shell, PAN@BMMs with strong fluorescence and good dispersibility were prepared. Their mesoporous features and physicochemical properties were extensively characterized via XRD patterns, N-2 adsorption-desorption analysis, SEM/TEM images, TGA profiles, and FT-IR spectra. In particular, their mass fractal dimension (d(m)) features based on SAXS patterns combined with fluorescence spectra were successfully obtained to evaluate the uniformity of the fluorescence dispersions, showing that the d(m) values increased from 2.49 to 2.70 with an increase of the AN-additive amount from 0.05 to 1%, along with the red shifting of their fluorescent emission wavelength from 471 to 488 nm. The composite (PAN@BMMs-I-0.1) presented a densification trend and a slight decrease in peak (490 nm) intensity during the shrinking process. Its fluorescent decay profiles confirmed two fluorescence lifetimes of 3.59 and 10.62 ns. The low cytotoxicity obtained via in vitro cell survival assay and the efficient green imaging performed via HeLa cell internalization suggested that the smart PAN@BMM composites are potential carriers for in vivo imaging and therapy.

Abstract ：
Clinoptilolite (CP) was successfully synthesized via a hydrothermal route in the presence of polyethylene glycol (PEG), and it was then delaminated by washing using Zn2+ containing acid. HKUST-1, as one kind of the Cu-based MOFs, showed a high CO2 adsorption capacity owing to its large pore volume and specific surface area. In the present work, we selected one of the most efficient ways for preparing the HKUST-1@CP compounds via coordination between exchanged Cu2+ and ligand (trimesic acid). Their structural and textural properties were characterized by XRD, SAXS, N-2 sorption isotherms, SEM, and TG-DSC profiles. Particularly, the effect of the additive PEG (average molecular weight of 600) on the induction (nucleation) periods and growth behaviors were detailed and investigated in the hydrothermal crystallization procedures of synthetic CPs. The corresponding activation energies of induction (E-n) and growth (E-g) periods during crystallization intervals were calculated. Meanwhile, the pore size of the inter-particles of HKUST-1@CP was 14.16 nm, and the BET specific area and pore volume were 55.2 m(2)/g and 0.20 cm(3)/g, respectively. Their CO2 and CH4 adsorption capacities and selectivity were preliminarily explored, showing 0.93 mmol/g for HKUST-1@CP at 298 K with the highest selective factor of 5.87 for CO2/CH4, and the dynamic separation performance was evaluated in column breakthrough experiments. These results suggested an efficient way of preparing zeolites and MOFs composites that is conducive to being a promising adsorbent for applications in gas separation.

Abstract ：
The random lamellae of the synthetic CP were synthesized with a hydrothermal approach using o-Phenylenediamine (OPD) as a modifier. The decreases in the order degree of the CP synthesized in the presence of the OPD resulted from the loss of long-range order in a certain direction. Subsequently, the ultrasonic treatment and washing were conducive to further facilitate the disordered arrangements of its lamellae. The possible promotion mechanism regarding the nucleation and growth behaviors of the sol-gel particles was proposed. The fractal evolutions of the aluminosilicate species with crystallization time implied that the aluminosilicate species became gradually smooth to rough during the crystallization procedures since the amorphous structures transformed into flower-like morphologies. Their gas adsorption and separation performances indicated that the adsorption capacity of CO2 at 273 K reached up to 2.14 mmol & BULL;g(-1) at 1 bar, and the selective factor (CO2/CH4) up to 3.4, much higher than that of the CPs synthesized without additive OPD. The breakthrough experiments displayed a longer breakthrough time and enhancement of CO2 uptake, showing better performance for CO2/CH4 separation. The cycling test further highlighted their efficiency for CO2/CH4 separation.

Abstract ：
The amine (NH2)-functionalized UiO-66 was successfully anchored on disorderly layered clinoptilolite (CP) via surfactant (poly(ethylene glycol) (PEG) and poly(vinylpyrrolidone) (PVP))-assisted induction. The structural features and physicochemical parameters of the resultant UiO-66-on-CPs were characterized by powder X-ray diffraction (XRD) patterns, scanning/transmission electron microscopy (SEM/TEM) images, Fourier transform infrared (FT-IR) spectra, N-2 sorption isotherms, and small-angle X-ray scattering (SAXS) patterns. The results demonstrated that the growth of UiO-66-NH2 nanoparticles facilitated the disorder degree of the crystal plane of CP along the a-axis, while the addition of PEG in the hydrothermal synthesis system of CP was conducive to the formation of a flower-like microstructure and the introduction of PVP was beneficial to the nucleation and growth of UiO-66-NH2 nanoparticles with a small size (40 nm) on the surfaces of the obtained CP-PEG lamellas. Finally, the gas-selective adsorption and separation performances of CO2 and CH4 were evaluated using the synthesized disorderly layered UiO-66-on-CP heterostructures as adsorbents, indicating that the NH2-functionalized UiO-66-on-CP exhibited a superior selective factor (3.66) of CO2/CH4. These results elucidated that the proposed approach is a promising strategy for constructing MOF-on-zeolite heterostructures, which may open an avenue to expand CP application and improve their performance.

Abstract ：
Three kinds of the bipyridine-proline chiral ligands as highly active species were successfully introduced on Zn-modified mesoporous silica nanomaterials (BMMs, MCM-41, and SBA-15) via the covalent attachment and coordination methods. Their microstructural features and physicochemical properties were extensively characterized via XRD patterns, SEM/TEM images, TGA profiles, FT-IR and UV-Vis spectra. In particular, their fractal features, the pair distance distribution function, and the Porod plots were evaluated thoroughly on the basis of the SAXS data. Meanwhile, their catalytic performances for asymmetric aldol reactions between p-nitrobenzaldehyde and cyclohexanone were evaluated. The results indicated that the bimodal mesoporous BMMs-based samples with short worm-like mesoporous channels possessed both mass and surface fractal features, whereas the MCM-41- and SBA-15-based samples with long-range ordered structures only showed surface fractal features. The influences of various reaction parameters, including the textures of the mesoporous silicas, the structures of the used chiral ligands, and the molecular volumes of aldehydes, on the catalytic activities (yield) and stereoselectivities (dr and ee) were investigated thoroughly. The results showed satisfactory activities (yields) and better stereoselectivity (dr and ee) in comparison with the homogeneous catalytic system using Z as the catalysts. In particular, the 3(rd) recycle catalytic performances of the Z-immobilized heterogeneous catalysts retained high catalytic yields (around 80%) and ee values of 28%. These phenomena were well interpreted by the essential relationships between the fractal characteristics of these heterogeneous catalysts and their catalytic activities.

Abstract ：
Various cation-exchanged clinoptilolites (M-CPs, M = Li+, Cs+, Ca2+, Sr2+) were prepared, and their exchanged thermodynamic (and kinetic) properties and adsorption performances for CH4, N-2, and CO2 were investigated. The results demonstrated that the relative crystallinity of M-CPS decreased with the increase of exchange times. Their chemisorbed water weight loss gradually increased with the increasing exchange times, except that of Cs-x-CP. The Delta(r)G(m)(theta) values of exchange process of Li+, Cs+, Ca2+, or Sr-2 presented the increased trend with the enhanced exchange times, but they decreased as the temperature increased. The negative Delta(r)G(m)(theta) values and the positive Delta H-r(m)theta and Delta S-r(m)theta values suggested that the exchanged procedure belonged to spontaneous, endothermic, and entropy-increasing behaviors; their kinetic performances followed a pseudo-second-order model. However, the calculated E-a values of exchange process showed the increased tendencies with the enhanced exchange times, indicating that the exchange process became more difficult. Finally, the preliminary adsorption results indicated that the maximum adsorption amount at 273 K and 1 bar was 0.51 mmol/g of CH4 and 0.38 mmol/g of N-2 by (Na, K)-CP, and 2.32 mmol/g of CO2 by Li-6-CP.
