Abstract

Abstract: 5% Ag0.9Pd0.1 nanoparticles have been deposited on top of Bi2MoO6 nanoplates for visible-light-driven photocatalysis by photoreduction deposition method. Phase, morphology, and oxidation state have been characterized by X-ray diffraction, transmission electron microscopy, X-ray photoelectron spectroscopy, Fourier transform infrared spectrophotometry, and Raman spectroscopy. Good distribution of spherical bimetallic AgPd nanoparticles has been supported on top of orthorhombic Bi2MoO6 nanoplates. The photocatalytic efficiencies of as-prepared photocatalysts have been studied through the degradation of rhodamine B (RhB) under visible light irradiation. The heterostructure 5% Ag0.9Pd0.1/Bi2MoO6 nanocomposites have the degradation efficiency better than pure Bi2MoO6 nanoplates due to the formation of Schottky barriers, localized surface plasmon resonance (LSPR) effect, and good electronic diffusion through the Ag0.9Pd0.1/Bi2MoO6 interfaces.
