Bimetallic AgPd nanoparticles have been synthesized before, but the interfacial electronic effects of AgPd on the photocatalytic performance have been investigated less. In this work, the results of hydrogene volution suggest that the bimetallic AgPd/g-C 3 N 4 sample has superiora ctivity to Ag/g-C 3 N 4 and Pd/g-C 3 N 4 photocatalysts. The UV/Vis diffuse reflectances pectroscopy,X -ray photoelectron spectroscopy, CO adsorption diffuse reflectance FTIR spectroscopy,a nd FTIR results demonstrate that in the AgPd/g-C 3 N 4 ,t he surface electronic structures of Pd and Ag are changed, which is beneficial for faster photogenerated electron transfera nd greater H 2 Om olecule adsorption.I nsitu ESR spectra suggest that, under visible light irradiation,t here is more H 2 Odissociation to radicals pecies on the AgPd/g-C 3 N 4 photocatalyst. Furthermore, DFT calculations confirm the interfacial electronic effects of AgPd/g-C 3 N 4 ,that is, Pd dÀ ···Ag d + ,and the activation energyo fH 2 Om olecule dissociation on AgPd/g-C 3 N 4 is the lowest,w hich is the main contributor to the enhanced photocatalytic H 2 evolution.[a] Dr.Supporting information and the ORCID identification number(s) for the author(s) of this article can be found under: https://doi.
