CdS/graphtic carbon nitride （CdS/g-C3N4） hybrid materials were fabricated by thermal polymerization and hy- drothermal methods using Cd（CH3COO）2-2H2O, thioacetamide, and melamine as precursors. The structural and op- tical properties of the as-synthesized samples were investigated by X-ray powder diffraction, UV-Vis diffuse reflec- tance spectroscopy, scanning electron microscopy, transmission electron microscopy, etc. A coupled system toward the selective oxidation of benzyl alcohol to benzaldehyde and the reduction of nitrobenzene into aniline was used to estimate the photocatalytic performance of CdS/g-C3N4 composite photocatalysts under visible light illumination. Results indicate that the CdS/g-C3N4 sample exhibits an outstanding photocatalytic performance for selective oxida- tion of benzyl alcohol and reduction of nitrobenzene. Meanwhile, benzotrifluoride is the best reaction medium among the screened solvents. further research demonstrates that the selective oxidation of benzyl alcohol to ben- zaldehyde is induced by the photoexcited holes and the reduction of nitrobenzene into aniline is triggered by the photoexcited electrons. Additionally, the catalyst can be recycled several times without noticeable deactivation.

Ni-based phosphides(NiPx)composed of earth-abundant elements are promising cocatalysts to replace noble metals for photocatalytic H2 evolution reaction(HER).A safe,energy-saving,and compositioncontrollable synthesis of NiPx is still highly desired.A facile and mild solvothermal process was developed for the first time for selective synthesis of a series of NiPx,including Ni,Ni12P5,Ni2P/Ni12P5,Ni/Ni2P and Ni2P,through controlling the dosage of NaBH4 and *** phosphidation process was mainly composed of(1)a sequential reduction of Ni2+to Nj0 and(H2PO2)-to P(around the formed Ni0)triggered by NaBH4,and(2)a final phosphidation between Nj0 and the in situ generated P *** photocatalytic HER performance of g-C3N4 can be substantially improved with the decoration of NiPx(3 wt%)as the separation of photoinduced charge carriers can be promoted and some active sites with low over-potential for HER can be *** cocatalytic efficiency of NiPx is mainly determined by P ***2P with a high ratio of P consequently exhibits the highest HER performance(215.1 umol g-1 h-1),which is almost six times higher than that of the pristine g-C3N4(35.6 umol g-1 h-1).Thus,as for the cocatalyst based on Ni phosphides,Ni2P is the preferable crystal phase and more efforts should be devoted to Ni2P to further optimize its structure,texture,and morphology in future works.

通过溶胶凝胶法制备了纳米晶TiO2光催化剂,并采用浸渍还原法制得相应负载贵金属的TiO2.利用XRD、UV-VIS-DRS和N2吸附等方法表征了催化剂的结构和织构,同时考察了反应气氛、Pt负载量、贵金属种类、葡萄糖投加量等对葡萄糖重整产氢的影响,比较了不同分子量碳水化合物在Pt/TiO2上光催化重整产氢的效率.结果表明,贵金属修饰对TiO2的晶相、比表面积的影响并不大,但能大大提高TiO2对糖类的产氢活性.当负载Pt的质量分数为1%时,样品对葡萄糖的光催化产氢活性最大;当负载等量贵金属且质量分数均为1%时,重整葡萄糖产氢的活性由高到低的顺序为:Pt/TiO2,Pd/TiO2,Au/TiO2,Rh/TiO2,Ag/TiO2,Ru/TiO2,其中Pt/TiO2与Pd/TiO2、Ag/TiO2与Ru/TiO2的活性相近.另外发现,O2对葡萄糖光催化重整产氢有抑制作用,而N2气氛对重整产氢有促进作用.多糖重整反应研究表明,Pt/TiO2对某些糖类有良好的光催化重整产氢活性,但产氢速率却随着多糖聚合度的增加逐渐降低.葡萄糖投加量实验表明,葡萄糖初始浓度对产氢反应速率的影响符合Langmuir-Hinshelwood关系式.
