Abstract
Herein, we report the production of a superior Mott-Schottky heterojunction that is based on PdAg nanowires (NWs) that grow in situ on graphitic carbon nitride (g-C 3 N 4 ). Due to the strong Mott-Schottky effect between PdAg NWs and g-C 3 N 4 , the heterojunction enhances the photocatalytic dehydrogenation of formic acid (FA) (TOF = 420 h -1 ) without additives and under visible light (λ > 400 nm) at 25 °C, which is the best value among all heterogeneous catalysts reported for the photocatalytic dehydrogenation of FA. The H 2 production rate is almost constant under the current reaction conditions. Detailed studies reveal that a favorable charge transfer from g-C 3 N 4 and Ag to Pd makes Pd electron-rich, which enhances the catalytic activity and stability of the heterojunction for the photocatalytic dehydrogenation of FA under visible light. Our studies open up a new route to the design of a metal-semiconductor heterojunction for visible light-driven photocatalytic dehydrogenation of FA. © 2019 The Royal Society of Chemistry.
