Synthesis and characterization of heteronanostructured Ag nanoparticles/MoO3 nanobelts composites

► α-MoO3 nanobelts have been successfully synthesized by conventional hydrothermal method at 180 °C for 24 h. ► Reduction of Ag+ ions to Ag nanoparticles using 1,2-propanediol as a reducing agent supports on α-MoO3 nanobelts. ► Decolorization of rhodamine-B of heteronanostructured Ag/MoO3 composites as a photocatalyst was investigated.
