Abstract ：
Gasoline vapor emissions from service stations significantly affect urban atmospheric. Despite the research on the mechanisms and effectiveness of gasoline vapor removal is limited, this study innovatively investigates the static and dynamic adsorption of xylene-a typical gasoline vapor and one of the most active secondary organic aerosol (SOA) species-by commercial activated carbon (AC). The results showed that the saturation static adsorption capacity (Q(e)) of 12 ACs varied from 0.9 to 870.7 mg/g, which correlated with the specific surface area (SSA) and pore volume. Among them, 11# and 12# ACs were identified as the most effective adsorbents for typical gasoline vapor removal. The maximum dynamic Q(e) increased from 301.5 to 414.3 mg/g when the initial xylene concentration rose from 918 to 2008 mg/m(3) for 11# AC, and from 201.4 to 406.2 mg/g when the initial xylene concentration increased from 589 to 2120 mg/m(3) for 12# AC. These findings implied a direct correlation between higher initial xylene concentrations and greater dynamic Q(e) values, with static Q(e) values surpassing dynamic values. The adsorption kinetics simulation were analyzed by the pseudo-first-order (PFO) and pseudo-second-order (PSO) kinetics. The kinetics results demonstrated that the PFO was more effective in characterizing the adsorption of xylene onto ACs (R-2 > 0.989), indicating that the adsorption of typical gasoline vapor by ACs primarily involves physical adsorption. The findings of static/dynamic adsorption and kinetics provide valuable guidance for practical applications of gasoline vapor removal in service stations.

Abstract ：
Cerium oxide (CeO2) was added to modified Ru/TiO2 catalyst by a two-step impregnation method for selective catalytic oxidation of ammonia (NH3-SCO). The low-temperature NH3 oxidation activity and N2 selectivity of the 1Ru/xCe-TiO2 catalyst were investigated with the result that both SCO activity and N2 selectivity were influenced by the amount of Ce. Specifically, the presence of 5 wt% CeO2 demonstrated a great promoting effect on both parameters, reaching an NH3 conversion and N2 selectivity of 97 % and 93 % at 180 degrees C, respectively. Various characterization methods indicated that the presence of CeO2 regulates the dispersion of the 1Ru/xCeTiO2 catalysts, changes the amount, strength and ratio of strong and weak acid sites on the catalyst surface, and promotes the formation of Ru-O-Ce bonds through the interaction between Ce and Ru species, which facilitates electron transfer and oxygen vacancy formation, thereby enhancing the oxidation ability of the catalysts. Furthermore, the results of in situ diffuse reflectance infrared Fourier transform spectroscopy indicated that the NH3-SCO reaction over the 1Ru/xCe-TiO2 catalysts follows the "internal" selective catalytic reduction (i-SCR) mechanism, involving the oxidation of NH3 into nitric oxide (NO) species and the reaction of -NH2 with in situformed NO to form N2.

Abstract ：
Cubic Cu2O micro/nanocrystals were successfully synthesized by liquid-phase reduction using copper salt of CuSO4 or CuCl2.2H2O, and glucose or ascorbic acid as reducing agent, respectively. The activity of the catalysts was evaluated by light-off curves of CO self-sustained catalytic combustion via temperature-programmed oxidation of CO (CO-TPO), with the results showing the activity of catalysts following the order of Cu2O-ClGLU > Cu2O-S-GLU > Cu2O-S-AA > Cu2O-Cl-AA, (Cl denotes CuCl2.2H2O, GLU denotes glucose, S denotes CuSO4 and AA denotes ascorbic acid, respectively), corresponding to the ignition temperature of 109 degrees C, 122 degrees C, 137 degrees C and 186 degrees C, respectively. The crystal structure, elemental valence, morphology and redox property of the prepared catalysts were analyzed by using various characterization techniques. Combined with in situ infrared spectrum, the CO self-sustained catalytic combustion over Cu2O catalysts mainly follows the Mars-van-Krevelen (M-v-K) mechanism: the adsorbed and activated CO reacts with lattice oxygen to yield CO2 and oxygen vacancy, and then the oxygen vacancy can be replenished by gaseous oxygen. Combined with catalytic performance of high-concentration CO, it is found that the catalysts prepared using glucose as reducing agent are more angular compared with ascorbic acid. The Cu2O-Cl-GLU synthesized with glucose and CuCl2.2H2O exhibits the best catalytic activity among all the catalysts tested, attributing to its more obvious edge and rough crystal surface. The unique structure of Cu2O-Cl-GLU leads to the high exposure rate and coordination unsaturation of atoms on the cubic Cu2O micro/nanocrystals that can improve the ability of activating gaseous O2 and low temperature reducibility, and consequently facilitating the catalytic activity.

Abstract ：
通过等体积浸渍法制备了一系列Mn-Ce/γ-Al_2O_3催化剂,并考察不同CeO_2负载量对MnO_2/γ-Al_2O_3催化剂催化氧化甲苯性能的影响。利用XRD、N_2吸脱附曲线、TEM、H_2-TPR、XPS和O_2-TPD等方法表征催化剂比表面积、表面形貌及氧化还原性能。结果表明，CeO_2的负载一定程度上降低了MnO_2/γ-Al_2O_3催化剂的比表面积,且催化剂仍保持介孔结构。CeO_2的存在增加了催化剂表面的化学吸附氧含量，其良好的储放氧能力促进了Mn~(3+)向Mn~(4+)的转化；Mn和Ce之间存在较强的协同作用,与MnO_x相邻的CeO_2更容易打开Ce—O键释放活性氧,加速氧化还原进程，Mn_(0.6)Ce_(0.4)/γ-Al_2O_3催化剂T10和T90与MnO_2/γ-Al_2O_3催化剂相比分别降低20和40℃。本研究可为VOCs催化氧化技术中低成本金属催化剂的开发提供参考。

Abstract ：
Monolithic catalysts are widely used in industrial catalysis. However, in the preparation of a monolithic catalyst, the traditional methods have some drawbacks such as low washcoat uploading ratio and poor uniformity. In the present work, the effects of Pd/Ce loading and catalyst components on the catalytic abatement of toluene were investigated. The acid treatment of the substrate, the particle size of the slurry and the dispersant on the uniformity of the washcoat and the catalytic performance were also explored. Characterisation was achieved via BET, SEM, zeta potential and laser grain-size analyses. The results showed that the catalytic activity of the catalyst increased with the increasing of the Ce content. It was found that the 0.2Pd-0.3Ce/gamma-Al2O3 catalysts had the best toluene catalytic activity. The pretreatment of the cordierite with 20% HCl could improve the properties of the cordierite. It was also found that reducing the particle size of the washcoat and adding dispersant PAA could effectively improve the stability of the suspension and the uniformity of the washcoat. When 20% HCl pretreatment was used, the toluene catalytic activity of the monolith catalyst prepared by cordierite increased, in which T-10 and T-90 decreased by about 5 degrees C. Decreasing the particle size and dispersant also promoted the efficiency of catalytic degradation.

Abstract ：
Metal Palladium species are efficiently used to degrade volatile organic compounds (VOCs). In this paper, the adsorption properties of toluene on Pd(111) and PdO(101) surfaces were theoretically studied using the first principle calculation. Adsorption energy, charge density, density of states and electron density difference were chosen as characteristics and were calculated to evaluate the adsorption capacity of toluene on Pd(111) and PdO (101) surfaces. The results showed that the interaction of toluene on the Pd(111) surface was stronger than on the PdO(101) surface. The dissociation pathway of toluene after adsorption was also determined; the results showed that the formation of benzyl radical through the reaction with a hydroxyl group on the Pd(111) and PdO (101) surfaces was investigated using density functional theory calculations. Compared with PdO(101) (0.63 eV), the dissociation of toluene on Pd(111) (0.19 eV) has a lower energy barrier, which indicated that the reaction between toluene and Pd(111) was easier to occur. Therefore, it provides the basis for the preparation of highperformance catalysts and the calculation of catalytic oxidation reaction paths in the future.

Abstract ：
Rare earth metals are strategic resources with potential applications in optics, metallurgy and catalysis. In recent years, single-atom site catalysts (SASCs) have attracted increasing attention owing to their 100% atom efficiency and unique catalytic performances. Over the past decade, rare earth elements, including rare earth metals and their oxides, have shown great potential in SASCs. However, systematic analyses of data are still handful. In this mini-review, the use of rare earth metals and their oxides in SASCs was summarized and the results are discussed. A particular focus was paid to the synthetic strategies, characterization of rare earth-containing SASCs, and applications as catalysis supports, promoters and active sites. Current issues faced by rare-earth metals and their oxides in SASCs, as well as future prospects were also provided. (C) 2020 Chinese Society of Rare Earths. Published by Elsevier B.V.

Abstract ：
In order to reduce the dust pollution caused by the coal mining process, a novel composite environmental dust suppressant for coal dust control was synthesized by corn straw, sodium carboxymethyl cellulose (CMC), and additives. This study focused on the preparation conditions of the dust suppressant, and the performances of which were investigated systematically. Response surface method (RSM) was used to optimize the raw material formulation and preparation parameters. The optimum mass ratio of straw, CMC, and alkali of the dust suppression was 65:20:15 (m/m), which was prepared under the conditions of the reaction time being 1.5 h and the rotation speed being 300 r/min. The pH of the dust suppressant was 8.0, and the state of which was suspension. Additives were benefited to enhance the suppressant performance, and the surface tension and the contact angle could decrease to 32.4 mN/m and 32.0 degrees. The suppressant has a maximum viscosity of 363.6 mPa center dot s, and the compressive strength could be up to 200 kPa. The hygroscopic rate could reach more than 4%. The wind erosion resistance could be up to 99 % at the wind speed of 14 m/s. After spraying the dust suppressant, the gap between particles was filled with dust suppressant, and the adjacent particles were bound by strong mechanical action.
