英文摘要Hydrogen, with the merits of zero emissions and high energy density, is one of the promising green energy sources. Seeking for high efficiency and low-cost catalysts is one of the key issues for hydrogen evolution and its practical applications. Nano-structured metal co-catalysts are widely used to improve the photocatalytic performance via surface electronic structure/properties optimization of the catalyst. Herein, we report ultra-fine (similar to 1 nm) Cu clusters decorated hydrangea-like TiO2 systems for photocatalytic hydrogen evolution. The pristine hydrangea-like TiO2 support shows a promising performance of hydrogen evolution (1.8 mmol.h(-1).g(-1)), which is similar to 10.7 times higher than that of the commercial P25 (168 mu mol.h(-1).g(-1)). After ultra-fine Cu clusters decoration, a maximal hydrogen evolution performance (3.7 mmol.h(-1).g(-1)) is achieved in the optimized system 6Cu-TiO2 (6 wt%). Experimental and theoretical studies demonstrate that the ultra-fine Cu clusters decoration could promote the charge separation and transfer process effectively. The Cu clusters also act as reaction sites for reduction of H2O to H-2. These results are of great importance for the study of Cu-based co-catalyst systems and also shed light on the development of other non-noble metal co-catalysts in photocatalysis hydrogen evolution.
