Ag 2 Mo 3 O 10 nanorods decorated with Ag 2 S nanoparticles have been synthesized by an anion‐exchange route. With thiourea as the sulfur source, sulfur ions replace [Mo 3 O 10 ] 2− units of active sites on the surface of Ag 2 Mo 3 O 10 nanorods, forming Ag 2 Mo 3 O 10 nanorods decorated with Ag 2 S nanoparticles. This induces enhanced absorption in the visible‐light region. Ag 2 S nanoparticles decorate the surface of Ag 2 Mo 3 O 10 nanorods uniformly with a suitable amount of thiourea. The Ag 2 S/Ag 2 Mo 3 O 10 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 Ag 2 S/Ag 2 Mo 3 O 10 nanoheterostructure displays good photocatalytic stability based on cyclic photocatalytic experiments.
