Although Au25 exhibits no catalytic activity toward A3-coupling reaction under the investigated conditions, the novel cadmium doped gold nanocluster Au26Cd5 shows high catalytic activity, as well as good recyclability and substrate tolerance for the same reaction.

      Thumbnail image of graphical abstract

      For the first time, the influence of the preparation gas atmosphere on the composition, crystalline and polymerization degree, and the activity of the g-C3N4 synthesized from thermal condensation of urea was investigated. Impressively, the g-C3N4 nano-sheets obtained under NH3 gas atmosphere exhibited much superior photo-catalytic activities to the prepared g-C3N4 in air or N2. Furthermore, we studied in depth the structure–property relationship in the system, and it was found that the synergistic effect of the larger surface area, the adjusted band energy structure and the good crystallization may be conductive to the higher separation of the electron–hole, thus leading to the wonderful performance for the g-C3N4-NH3. Notably, the method has the merits of the low cost, scalable production and environmental friendliness.

    1. Solvothermal Synthesis of TiO2/Bi2WO6 Heterojunction Photocatalyst with Optimized Interface Structure and Enabled Photocatalytic Performance

      Linpeng Jiang, Shujie Wang, Liyi Shi, Yin Zhao, Zhuyi Wang, Meihong Zhang and Shuai Yuan

      Version of Record online: 13 FEB 2017 | DOI: 10.1002/cjoc.201600563

      Thumbnail image of graphical abstract

      The TiO2/Bi2WO6 (TB) heterojunction interface structure was optimized via adjusting the ethylene glycol/water (EG/W) ratio. Since precursor TiO2 nano-particles cannot be well dispersed in EG compared with the water reaction solvent, it leads to self-agglomeration and decrease of the TiO2/Bi2WO6 interfaces. When EG/water mixture was used as the reaction solvent, sample TBEG/W comprises more plenty of and tighter contact interface between Bi2WO6 and TiO2, which is beneficial for promoting the photocatalytic efficiency. From the view of charge dynamics, the highest quantity of electron–hole pairs separated driven by optimized heterojunction interface between two semiconductors.

The constructed g-C3N4/PPy/Ag ternary composite showed increased photocatalytic activity caused by the synergistic effect of PPy and Ag toward tetracycline degradation in comparison with pure g-C3N4, PPy, g-C3N4/PPy and g-C3N4/Ag under visible light irradiation.

      Nickel is robust in hydrogen production via catalyzing steam reforming process. However, Ni-based reforming catalysts were prone to encounter deactivation due to carbon deposition. This paper describes the utilization of NiSn/CeO2 catalysts to suppress coke formation via introducing Ni-CeO2 interaction and the coverage of Sn on Ni surface. Although the addition of Sn suppressed the reforming activity of Ni/CeO2 in some degree, the stability of Ni/CeO2 could be improved when 0.25 wt% Sn was added. The influence of Sn addition on the performance of Ni/CeO2 catalysts in ethanol steam reforming was discussed in detail in this paper.

      Carbon and nitrogen species-involved TiO2 (CN-TiO2) was systematically synthesized by thermal condensation of cyanuric acid on the TiO2 surface. The CN-TiO2 photocatalyst was found to exhibit high photocatalytic activities for H2 production from alcoholic aqueous solutions under visible-light irradiation. It was emphasized that an enhancement of H2 production is associated with effective charge separations through the photo-excitation of highly dispersed carbon nitride coupled with TiO2 surface.

    6. A Novel CdS/g-C3N4 Composite Photocatalyst: Preparation, Characterization and Photocatalytic Performance with Different Reaction Solvents under Visible Light Irradiation

      Version of Record online: 12 JUL 2016 | DOI: 10.1002/cjoc.201600251

      Thumbnail image of graphical abstract

      CdS/graphtic carbon nitride (CdS/g-C3N4) hybrid materials were synthesized by thermal polymerization and hydrothermal methods using Cd(CH3COO)2·2H2O, thioacetamide, and melamine as precursors. Upon visible light irradiation, a coupled system toward the selective oxidation of benzyl alcohol to benzaldehyde and the reduction of nitrobenzene into aniline was realized by the as-synthesized photocatalyst. Results indicate that CdS/g-C3N4 sample exhibits an outstanding photocatalytic performance for selective oxidation of benzyl alcohol and reduction of nitrobenzene. Further study suggests that the selective oxidation of benzyl alcohol to benzaldehyde 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.
