One-dimensional ultrathin Pt/CeO₂/Bi₂WO₆ nanobelts with an exceptional photoelectrochemical performance have been controllably and delicately fabricated via a simple two-step method. The as-prepared nanobelts were systematically characterized by TG, XRD, FT-IR, SEM, HRTEM, BET, XPS, UV-vis, PL, TOC, HPLC and EIS. The photocatalytic activity of resultant samples has been determined sufficiently through decomposition of methylene blue (MB) and rhodamine B (RhB) dyes. The enhanced photocatalytic performance is significantly improved by loading of Pt nanoparticles (NPs) on CeO₂/Bi₂WO₆ nanobelts, and the optimal Pt content is also evaluated. In photocatalysis, the mechanism of ultrathin Pt/CeO₂/Bi₂WO₆ nanobelts for the visible light photocatalytic enhancement is thoroughly elucidated. The nanobelts with such attributes could not only lead to the faster development for constructing highly efficient photocatalysts but also aid in our understanding and optimization of their properties.
