Abstract
Abstract Plasmonic AgPd alloy nanoparticles (AgPd NPs ) decorated on single-layer carbon nitride (AgPd NPs /SLCN) for the designing of the Mott-Schottky junction were constructed with the ultrasonically assisted hydrothermal method and used toward photo evolution H 2 from formic acid (FA) at near room temperature (30 °C). The Pd atom contains active sites that are synergistically boosted by the localized surface plasmon resonance (LSPR) effect of Ag atoms, leading to considerably enhanced photocatalytic properties. The photoactive AgPd NPs /SLCN obtained supreme catalytic activity to produce 50 mL of gas (H 2 + CO 2 ) with the initial turnover frequency of 224 h -1 under light irradiation. The catalyst showed stable catalytic performance during successive cycles.
