Decoration of PdAg Dual-Metallic Alloy Nanoparticles on Z-Scheme α-Fe₂O₃/CdS for Manipulable Products via Photocatalytic Reduction of Carbon Dioxide.

ABSTRACT: Metal nanoparticles have been extensively used as co-catalysts in photocatalytic systems in order to pursue improvements in both reaction kinetics and selectivity. In this work, PdAg dual-metallic nanoparticles synthesized by the co-reduction method were decorated on a well-established α-Fe₂O₃/CdS Z-scheme photoactive material as a co-catalyst to study their performance for promoting the photoreduction of CO₂. Herein, α-Fe₂O₃ and CdS were in situ synthesized on fluorine-doped tin oxide (FTO) glass by hydrothermal and SILAR (successive ionic layer adsorption and reaction) methods, respectively. The direct Z-scheme charge transfer path between Fe₂O₃ and CdS and the effective electron migration toward the PdAg
