Abstract

Abstract: Ag2 Mo3 O10 nanorods decorated with Ag2 S nanoparticles have been synthesized by an anion‐exchange route. With thiourea as the sulfur source, sulfur ions replace [Mo3 O10 ] 2− units of active sites on the surface of Ag2 Mo3 O10 nanorods, forming Ag2 Mo3 O10 nanorods decorated with Ag2 S nanoparticles. This induces enhanced absorption in the visible‐light region. Ag2 S nanoparticles decorate the surface of Ag2 Mo3 O10 nanorods uniformly with a suitable amount of thiourea. The Ag2 S/Ag2 Mo3 O10 nanoheterostructure enhances the photocatalytic activity on the degradations of Rhodamine B and glyphosate under visible light. This enhancement is attributed to the improved absorption of visible light and effective separation of charge carriers in the nanoheterostructure. Meanwhile, the Ag2 S/Ag2 Mo3 O10 nanoheterostructure displays good photocatalytic stability based on cyclic photocatalytic experiments. Abstract : The nanoheterostructure Ag2 S/Ag2 Mo3 O10 was successfully synthesized by a simple anion exchange route using thiourea as a sulfur source. Ag2 S nanoparticles can disperse on the surface of Ag2 Mo3 O10 nanorods uniformly. The Ag2 S/Ag2 Mo3 O10 photocatalyst exhibited a high visible‐light‐driven photocatalytic activity on the degradation of Rhodamine B and glyphosate.
