Abstract ：
在光催化甲苯氧化降解是一种低能耗低成本高效率的VOCs末端处理手段,但是催化剂稳定性差的失活原因是光催化应用于VOCs治理中需要解决的问题。本文以TiO_2为载体通过溶胶凝胶法和NaBH4还原的方法分别引入Fe和Pd两种金属进行改性,通过双金属的协同作用,提高光生载流子的传递效率并提供更多的吸附位点,实现高效稳定的光催化甲苯氧化降解。

Abstract ：
静电自组装法制备的CdS QDs/BaSnO_3纳米复合材料显示出有效的可见光利用率和光催化NO氧化活性。实验结果表明,CdS QDs的负载极大地提高了光吸收范围光生电子-空穴对的和分离效率。原位DRIFTS测试表明,引入的Cd~(2+)可以为NO吸附和活化提供新的活性位点。同时,EPR测试表明,CdS QDs的引入诱导了·O_2~-的生成,这有利于促进NO的深度氧化。本研究为提高光催化NO去除效率同时抑制NO_2浓度提供了一种简单有效的合成方法和策略。

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 ：
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 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.

本发明公开了一种光助NO生成氨的Pd/四氧化三铁催化剂及其制备方法与应用，其是将Pd纳米粒子负载在具有光吸收的Fe3O4载体上，制得了所述负载型Pd催化剂。通过引入紫外光，利用光热耦合作用实现了Pd/Fe3O4催化剂在低温下优异的CO和NO转化率及NH3选择性。而传统的热催化反应通常要在较高温度才能有较好的活性和选择性。对于Pd/Fe3O4催化剂，同等条件下加光能够显著提高CO和NO的转化率和NH3的选择性，且与传统合成氨所需的高温高压条件相比，大大降低了反应所需的能耗。而Fe3O4中Fe2+和Fe3+之间的变价交替也有利于催化剂表面氧空位的循环。制备方法简单可行，更有利于推广应用。
