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 H₂ 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 (H₂ + CO₂) with the initial turnover frequency of 224 h^-1 under light irradiation. The catalyst showed stable catalytic performance during successive cycles.
