The effect of Pt contents loaded on the Bi2MoO6 nanoplates was investigated through the photodegradation of rhodamine B (RhB) illuminated by visible radiation. Face-centered cubic (FCC) metallic Pt nanoparticles were supported on the surface of orthorhombic Bi2MoO6 nanoplates with very good distribution by a microwave-assisted deposition method. The photocatalytic performance of Bi2MoO6 nanoplates was increased with increasing the loaded Pt nanoparticles from 1% to 10%. Upon further increasing the loaded Pt nanoparticles to 15%, the photocatalytic performance for the degradation of RhB was significantly reduced. In this research, 10% Pt/Bi2MoO6 nanocomposites have the highest photocatalytic activity because Pt nanoparticles are very good electrical conductors that play the role of enhancing photocatalytic reaction rate. Research Highlights Pt/Bi2MoO6 nanocomposites were prepared by microwave-assisted deposition method. They played the role in degrading rhodamine B illuminated by visible radiation. The promising material used for wastewater treatment.
