摘要：The rational design of novel and efficient heterojunction photocatalysts is recognized as one of the significant challenges for achieving highly efficient solar-to-chemical energy conversion. Herein, we report a novel Ta3N5/ ZnO core-shell nanofibers heterojunction photocatalyst for boosting photocatalytic H2 evolution activity through the combining of electrospinning and ALD process. Based on the combined strategies of nanostructure engi-neering and heterojunction, the enhanced photocatalytic activity of Ta3N5/ZnO hybrid sample is attributed to the synergistic effects of increased reaction sites and improved charge transfer. The optimized Ta3N5/ZnO-150 core-shell nanofibers heterojunction photocatalyst exhibited the highest photocatalytic hydrogen production activity of 1193.75 mu mol g-1 h-1, which is about 7 times higher than the bare Ta3N5 nanofibers, and also superior to the most of Ta3N5-based photocatalysts ever reported.
