Abstract

Pt nanoparticles decorated with rose-like Bi₂O₂CO₃ configurations were synthesized via a simple photoreduction method at room temperature. The structure, morphology, optical and electronic properties, and photocatalytic performance of the as-prepared materials were characterized. Compared to pure Bi₂O₂CO₃, the Pt/Bi₂O₂CO₃ photocatalysts show better performance in decomposing RhB, BPA and OTC under visible light (λ > 420 nm). The enhanced photocatalytic activity of Pt/Bi₂O₂CO₃ could be attributed to the modification in light absorption (λ > 420 nm) charge migration and the separation of photo-generated electrons (e⁻) and holes (h⁺). Free radical trapping experiments demonstrated that the main active species of the catalytic reaction are different in decomposing RhB and BPA.
