摘要：Highly-active heterojunctions hold the pivotal function in photocatalytic hydrogen evolution reaction (HER). Herein, Ta3N5@ReS2 photocatalysts are rationally designed via the combination of template-assisted, hydrothermal and solution-adsorption processes, in which few-layered ReS2 nanosheets are anchored on hollow Ta3N5 nanospheres with intimate contact for charge transfer. The photocatalytic H-2 production rate of Ta3N5@ReS2 heterojunctions reaches 739.4 mu mol g(-1) h(-1), which is similar to 16 times higher than that of the bulk Ta3N5 counterpart, and superior to those of Ta3N5-based photocatalysts ever reported. According to the experimental results and theory calculation, it is proposed that such designed Ta3N5@ReS2 heterojunctions could be highly effective for enhancing the absorptivity of light, improving charge separation and transfer, as well as increasing edge active sites for HER, thus leading to the promoted H-2-evolution kinetics.
