Pt nanoparticles decorated rose-like BiOCO configurations for efficient photocatalytic removal of water organic pollutants.

Pt nanoparticles decorated with rose-like BiOCO configurations were synthesized 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 BiOCO, the Pt/BiOCO photocatalysts show better performance in decomposing RhB, BPA and OTC under visible light ( > 420 nm). The enhanced photocatalytic activity of Pt/BiOCO could be attributed to the modification in light absorption ( > 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.
