Pt nanoparticles decorated with rose-like Bi
O
CO
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 Bi
O
CO
, the Pt/Bi
O
CO
photocatalysts show better performance in decomposing RhB, BPA and OTC under visible light (
> 420 nm). The enhanced photocatalytic activity of Pt/Bi
O
CO
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.
