▎ 摘　　要

A new nanostructure photocatalyst, incorporating Ag and reduced graphene oxide (rGO) with LaMnO3-nanorods have been fabricated via two-step synthetic approaches by using Cetyltrimethyl Ammonium Bromide (CTAB) as a template via a simple hydrothermal reaction and the decoration of Ag nanoparticles is through a traditional silver mirror reaction. The characteristic of the materials are examined by XRD, TEM, FE-SEM and XPS. The results confirm that the LaMnO3 nanorods are perovskite phase and uniform dispersed on the surface of rGO. The Ag nanoparticles is deposited the surface of LaMnO3-nanorods with its metal form. The Ag/LaMnO3-nanorods/rGO exhibit an excellent performance in the photodegradation of Direct Green BE under the UV-vis irradiation. As an electron capture agent, metal Ag can capture the e-that transported along the LMO-NR, thereby leading to effective separation of the e(-)-h(+) pairs and accelerate the transfer of surface charge, which is further demonstrated by the Photoluminescence (PL) spectra, cyclic voltammetry (CV) and AC impedance spectra.
