Abstract ：
Devising robust S-scheme photocatalysts is of central importance for achieving high-efficient micropollutant decontamination. However, the conscious optimization of S-scheme system with high performance remains a prime challenge. Herein, carbon quantum dots (CDs) and Mn 0.5 Cd 0.5 S (MCS) are mounted on BiOBr (BOB) microspheres, establishing an advanced S-scheme heterojunction with interfacial Bi-S bond. The interfacial Bi-S bonds function as superb channels at atomic-scale to abate the energy barrier for S-scheme charge transportation. Meanwhile, CDs serve as electron collectors to preserve highly reductive electrons from MCS, further augmenting the spatial separation of photo-carriers. Therefore, the optimized CDs/MCS/BOB (MBC) heterojunction manifests significantly strengthened tetracycline hydrochloride (TC) destruction activity and its reaction rate constant is approximately 3.1, 2.2, 2.1, and 1.5 folds that than that of MCS, BOB, BOB/CDs and MCS/BOB. In addition, MBC exhibits high stability and significant resistance to environmental interferences. The toxicology evaluation confirms the effective abatement of toxicity of TC after treatment. This achievement demonstrates the benefits of CDs-optimized S-scheme photosystems with chemical bonds for photocatalytic water decontamination.

Abstract ：
To realize the rapid separation of photogenerated carriers in photocatalytic reactions, large-sized porous carbon nanosheets with Pt dots were utilized as cocatalysts and coupled with TiO2 particles to construct photocatalytic systems. The optimized photocatalytic H-2 yield is similar to 108 times higher than that of TiO2, fully demonstrating the important role of large-sized porous carbon nanosheets with Pt dots for fast charge separation. The shift of the main peak in high-resolution X-ray photoelectron spectroscopies (XPS) verifies the electron transfer from TiO2 to porous carbon nanosheets. The dense distribution of photo-induced Pt deposition on porous carbon nanosheets confirms that active centers for H-2 evolution are mainly located on porous carbon nanosheets. Our work here provides the practicability of constructing large-sized conductive materials as cocatalysts for fast charge separation in photocatalytic reactions.

Abstract ：
Thedesign of photocatalysts plays a central role in determiningthe photocatalytic H-2 yield. Here, we used a design strategythat is different from conventional methods to prepare our photocatalyticsystems. Large porous carbon aerogels (CA) with rich surface areaswere used to receive photogenerated electrons. TiO2 quantumdots were used as photocatalysts and anchored on large porous CAsto form CA@TiO2 systems. The H-2 yield of theoptimized CA@TiO2 composite is & SIM;2.1 mmol/g, & SIM;11times higher than that of pure TiO2 quantum dots. High-resolutionX-ray photoelectron spectroscopy and high-angle annular dark-fieldscanning transmission electron microscopy demonstrate that the photogeneratedelectrons can be easily transferred from TiO2 quantum dotsto porous CAs. Thus, efficient charge separation can be realized forthe succeeding highly efficient H-2 evolution. Our resultshere provide a different way from conventional methods to design photocatalyticsystems with high H-2 yield.

Abstract ：
Cocatalysts in photocatalytic systems play an important role in achieving efficient charge separation. These cocatalysts usually have a small size and are generally anchored onto main catalysts. They are taken as active centers to receive photogenerated electrons for water splitting. However, their high loading concentration usually leads to the degradation of water splitting. Here, we present a different strategy for the design of the main catalyst and cocatalyst. We used small-sized ultrathin cadmium sulfide (CdS) nanosheets as the main catalysts and anchored them onto large-sized N -doped carbon nanotubes with encapsulated cobalts. The photocatalytic hydrogen production of our optimized composite is similar to 21.8 mmol/g, similar to 3 times higher than that of pure CdS. Mechanism study shows that photoelectrons can be transferred from CdS to N-doped carbon nanotubes, thus achieving fast charge separation and efficient hydrogen production.

Abstract ：
Small-sized particles are usually used as cocatalysts and anchored onto a large-sized photocatalyst for fast charge separation. However, the current problem for the design of photocatalysts is that a high loading of small-sized particles leads to full coverage of photocatalysts, resulting in the decrease of hydrogen production. Here, we propose a different way to construct photocatalytic systems. Large-scale carbon nanotubes with doped nitrogen (N-CNTs) are used to couple with TiO2 quantum dots. The H-2 yield for our optimized photocatalytic system is similar to 146 mmol/g. With further considering the light-induced thermal effect, the H-2 yield reaches up to similar to 320.6 mmol/g. Electrochemical and spectroscopic data show that large-sized N-CNTs can offer abundant active sites to realize the rapid carrier separation for tremendously improved hydrogen production.

Abstract ：
A key challenge in photocatalysts is their rapid recombination of photo-generated elec-tron-hole pairs. To decrease the recombination probability, significant studies have been devoted to increasing potential active sites of photocatalytic systems for fast charge separation. Here we demonstrate a strategy to boost active sites that is different from conventional approaches, in which large-sized Mxene nanosheets were employed as co-catalysts, while small-sized CdS nanosheets were used as photocatalysts forming effec-tive nanocomposites. Based on our designed strategy, the enrichment of transfer routes guides the fast separation of electrons from CdS nanosheets and transferred onto large-sized Mxene nanosheets. The visible-light-driven hydrogen production of our innova-tively designed composites has been improved from 2.8 mmol/g of pure CdS nanosheets to 17.5 mmol/g of the CdS@Mxene optimized composite. The obvious improvement of hydrogen production verifies the feasibility of our design strategy as a unique way to our tactic here can be extended to the design of other kinds of photocatalytic systems.

Abstract ：
The common strategy for the design of photocatalytic materials is to load small-sized cocatalysts onto large-sized photocatalysts for efficient charge separation. In this study, a new design strategy is presented to anchor smallsized TiO2 photocatalysts onto large-sized Ti3C2-Mxene cocatalysts, which can provide enriched active sites to receive photo-generated electrons, thus achieving fast charge separation. Based on this strategy, the 4h-hydrogen production rate of the optimized photocatalytic system (62.5 mu mol) is 15.2 times higher than that of pure TiO2 (4.1 mu mol), strongly demonstrating the feasibility of our design strategy. The strategy here presents an effective way to design novel photocatalytic systems with superior photocatalytic properties.

Abstract ：
The structural stability of high-entropy alloys (HEAs) is closely related to their mechanical properties. The precise control of the component content is a key step toward understanding their structural stability and further determining their mechanical properties. In this study, first-principle calculations were performed to investigate the effects of different contents of each component on the structural stability and mechanical properties of Co-Cr-Fe-Ni HEAs based on the supercell model. Co-Cr-Fe-Ni HEAs were constructed based on a single face-centered cubic (FCC) solid solution. Elemental components have a clear effect on their structure and performance; the Cr and Fe elements have an obvious effect on the structural stability and equilibrium lattice constant, respectively. The Ni elements have an obvious effect on stiffness. The Pugh ratios indicate that Cr and Ni addition may increase ductility, whereas Co and Fe addition may decrease it. With increasing Co and Fe contents or decreasing Cr and Ni contents, the structural stability and stiffness of Co-Cr-Fe-Ni HEAs are improved. The structural stability and mechanical properties may be related to the strength of the metallic bonding and covalent bonding inside Co-Cr-Fe-Ni HEAs, which, in turn, is determined by the change in element content. Our results provide the underlying insights needed to guide the optimization of Co-Cr-Fe-Ni HEAs with excellent mechanical properties.

Abstract ：
Photocatalytic hydrogen production from water splitting has received considerable attention in recent years. The bottle-neck issue for hydrogen production efficiency is the relative slow charge separation and efficient hydrogen evolution. Currently, the major strategy for developing catalysts is to anchor small noble-metal cocatalysts onto relatively large photocatalysts. In this study, extremely small photocatalysts of TiO2 quantum dots were loaded onto the low-cost micro-sized cocatalysts of porous NiO/NiS2 nanosheets, promoting the rapid charge separation of photogenerated electrons from small-sized photocatalysts to large-sized cocatalysts. The size of cocatalysts is three orders of magnitude larger than that of photocatalysts. The hydrogen production of designed catalysts is similar to 16 times higher than that of pure TiO2 photocatalysts, clearly demonstrating the critical role of large-sized porous cocatalysts. Our game-changing strategy provides a distinctive approach to design new kinds of photocatalysts with rapid charge separation and highly efficient hydrogen evolution.
