Abstract
A novel nano-heterostructure of AgI/Bi2MoO6 photocatalyst was successfully synthesized via a facile deposition-precipitation method. The samples were systematically characterized by X-ray diffraction, scanning and transmission electron microscopy, X-ray photoemission spectroscopy, UV-Vis absorption spectroscopy, and photoluminescence spectra. While sole Bi2MoO6 or AgI showed poor activity toward photocatalytic rhodamine B degradation, the nano-heterostructure was found with superior performance. The AgI/Bi2MoO6 composite with an optimal content of 20 wt% AgI exhibited the highest photocatalytic degradation rate. Rhodamine B was totally degraded within 75 min visible-light irradiation. Moreover, the hybrid photocatalyst also showed a fairly good stability for several-cycle reuse. This study indicates that the AgI/Bi2MoO6 nano-heterostructure can be used as an effective candidate for photocatalytic degradation of organic pollutants.
