Abstract ：
Tungsten oxide (WO3) and copper oxide (CuO)/WO3 samples were prepared, and their photocatalytic performance towards the reforming of CH3OH to hydrogen was compared under visible light irradiation at ambient temperature. CuO/WO3 had an approximately 64 times higher hydrogen production activity than bare WO3. CH3OH accepted electrons from WO3 but provided electrons to CuO/WO3 thin films, indicating that the hydrogen production from CH3OH was related to electron transfer during CH3OH adsorption. The characterization results showed that Cu exists in a mixed-valence state in CuO/WO3, which activated the lattice oxygen of WO3 to form the corresponding interfacial oxygen vacancies (VOs). The oxygen atom of CH3OH was fixed at VOs sites, which facilitated the cleavage of the O-H bond. Cu2+ sites favored the cleavage of the C-H bond in CH3OH because VOs fixed the oxygen atom. Then, the production of hydrogen via these two processes was accompanied by the transfer of electrons from CH3OH to Cu2+ sites at the interface. This was followed by hydrogen production after accepting photogenerated electrons from WO3. The reason for the low catalytic activity of the WO3 support was that it contained no VOs nor Cu2+ sites to oxidize CH3OH to produce more protons. This study provides an approach to improve catalysts used for the photocatalytic reformation of methanol.

Abstract ：
A BaSnO3 sample loaded with CdS quantum dots (CdS QDs/BaSnO3) was prepared by an electrostatic selfassembly method. The obtained CdS QDs/BaSnO3 nanocomposites exhibited an efficient visible light utilization and photocatalytic NO oxidation activity. The experimental results revealed that the loading of CdS QDs tremendously improved the light absorption range and the separation efficiency of photogenerated electron-hole pairs. In-situ DRIFTS tests demonstrated that the introduced Cd2+ could provide new active sites for NO adsorption and activation. Simultaneously, the EPR test showed that the introduction of CdS QDs induced the generation of .O2-, which was conducive to promoting the deep oxidation of NO. This study provides a facile and effective synthesis method and strategy for improving the photocatalytic NO removal efficiency while significantly suppressing the NO2 concentration.

Abstract ：
The photocatalytic non-oxidative coupling of methane (NOCM) process is a desirable reaction that uses solar energy to convert methane into an equal proportion of ethane and hydrogen. However, most current photocatalysts suffer from low product yields and selectivity due to the over-oxidation of methane or catalyst deactivation by coke deposition. In this study, a Ag/In2O3 photocatalyst was synthesized by a simple deposition precipitation method for the non-oxidative coupling of methane in a batch reactor under photoirradiation at room temperature and atmospheric pressure. Ethane yields of up to 450.26 & mu;mol g(-1) h(-1) with a high selectivity of 88% were achieved. The characterization results showed that Ag+ species were stably loaded in oxygen vacancies on the In2O3 carrier. The Ag+ accepted the photogenerated electrons from In2O3, which inhibited the recombination of the electrons and photogenerated holes, while the methane was oxidized by the holes to ethane. This study offers a new insight into the design of photocatalytic NOCM reactions.

Abstract ：
A photothermal catalytic system comprising Cu/CeO2 was applied to the reaction between NO, CO and H2O for the production of NH3 under visible-light irradiation. High NO conversion (94.4%) and NH3 selectivity (66.5%) were achieved over Cu/CeO2 in the presence of H2O at 210 & DEG;C. Visible light further improved the conversion of NO (97.7%) and selectivity for NH3 (69.1%). The quasi-situ EPR and in-situ DRIFTS results indicated that CO initially reacts with H2O to form an HCO3* intermediate, which then decomposes into CO2 and activated H*. Finally, NO reacts with activated H* to produce NH3. The localized surface plasmon resonance effect of Cu nanoparticles induced by visible light promotes the decomposition of HCO3* to CO2 and H*, while regenerating oxygen vacancies (OVs, H2O activation sites) at the CeO2 sites, resulting in enhanced NH3 production. This study offers a convenient approach for NH3 production under mild conditions. Published by Elsevier B.V. All rights reserved.

Abstract ：
To resolve the pollution flashover problem of insulators, a novel application of nanosized TiO2 film to improve the ceramic insulator performance under contaminated conditions has been successfully developed. Compared with the uncoated insulator, TiO2 -coated insulator exhibits an enhanced self-cleaning performance induced by the photocatalysis and hydrophilicity of TiO2 film in the heavily contaminated surroundings. Moreover, the TiO2 -coated insulator also presents a better electric performance in power-frequency puncture voltage, power-frequency puncture voltage in dielectric oil, wet power-frequency flashover voltage, lightning impulse withstand voltage, and the artificial pollution flashover voltage due to the semi-conducting property of TiO2 film to make the distribution of the electric field more even. The synergy between these two effects helps to promote the performance of TiO2 -coated insulators for anti-pollution flashover. © 2023 WILEY-VCH GmbH.

Abstract ：
Porous organic cages (POCs) have shown great potential in many applications, and post-synthetic modification (PSM) has been confirmed to be an effective strategy to tailor their structures and related functionalities. However, it is extremely challenging to develop a general platform for simple-to-make functional POCs for advanced applications by PSM method. Herein, we reported that octahedral calix[4]resorcinarene-based hydrazone-linked porous organic cage (HPOC-401) provides an excellent platform for post-synthetic metalation by various transition metal (TM) ions under mild conditions due to the abundance of coordination sites in its skeleton. Such metalated products (HPOC-401-TM) exhibit Brunauer-Emmett-Teller (BET) surface area up to 1,456 m(2) g(-1), much higher than that of the pristine HPOC-401, which has a BET value of 474 m(2) g(-1). Moreover, the metalation and porosity increases further influence their gas capture, separation, as well as catalytic performance. For instance, HPOC-401-TM products exhibit higher CO2, H-2, and C2 hydrocarbon gas uptake, as well as higher C2H6/C2H4 selectivity than HPOC-401. Moreover, the HPOC-401-TM also shows better catalytic performance in the cycloaddition of CO2 with epoxides compared to HPOC-401. These findings uncover a simple yet effective approach for modifying the porosity characteristics of organic cages, which will undoubtedly expand their future implementations.

Abstract ：
NH_3不仅是关键的工业化学原料,而且是未来可再生能源的无碳燃料和可运输的载体.目前,工业合成NH_3仍然以传统的Haber-Bosch反应为主,需要300-500°C的高温和20-30 MPa的压力.为克服这些缺点,研究者设计了NO-CO-H_2O反应体系.在该反应中,通过有毒气体CO在H_2O存在的条件下将NO还原成NH_3,这是一种近乎理想的生产NH_3的方法.目前,已经报道了Pt/Al_2O_3在NO-CO-H_2O反应中具有较高的NH_3选择性,但反应温度(400°C)仍然较高,不利于实际应用.因此,在低温条件下引入光照,通过光辅助热催化NO-CO-H_2O反应来获得NH_3产品,是一种极具发展潜力的方法.研究人员通过密度泛函理论(DFT)研究发现, Cu在NO还原反应中具有很高的活性和NH_3选择性,且Cu在水煤气(CO+H_2O)变换反应中具有较高的活性.CeO_2具有丰富氧空位同时能充当碳酸盐的储存位点,还可以起到稳定分散铜的作用.因此,本文将具有局域表面等离子体共振(LSPR)效应的金属Cu负载在具有氧空位的棒状CeO_2上形成Cu/CeO_2纳米复合材料,并研究了其催化NO-CO-H_2O反应性能.结果表明, Cu/CeO_2不仅在100-270°C下表现出较好的CO和NO去除效率,且可以选择性地催化还原NO为NH_3.其中, 5%Cu/CeO_2表现出最优催化活性, 210°C时NO转化率为94.4%和NH_3选择性为66.5%.在相同温度下,可见光可以进一步提高NO转化率(97.7%)和NH_3选择性(69.1%).通过对NO-CO-H_2O反应进行分步活性测试,发现该反应的主要过程由水煤气变化反应生成活性H*及其进一步与NO发生选择性催化还原反应两部分组成.准原位电子顺磁共振、原位漫反射傅立叶变换红外光谱和密度泛函理论计算表明,在Cu/CeO_2上NO-CO-H_2O的反应机理是CO首先与H_2O反应形成HCO_3*中间物,然后分解成CO_2和活性H*,最后NO与活性H*反应产生NH_3.而可见光诱导Cu的LSPR效应能有效地将催化剂的光吸收范围拓宽至可见光,同时其产生的热电子能有效提高催化剂表面电子密度,从而促进了HCO_3*分解为CO_2和活性H*;另外,在CeO_2上再生了氧空位(H_2O的活化点),进而增加了NH_3产量.综上,本文提供了一种在温和条件下合成NH_3的可行性方法,能为合成NH_3工艺提供一种新途径.
