Efficient Photocatalytic Decomposition of Organic Contaminants over CaBi 2 O 4 under Visible‐Light Irradiation

Green degradation: Organic contaminants such as volatile organic compounds and dyes (e.g. acetaldehyde and methylene blue (MB)) can be photocatalytically degraded over a novel CaBi2O4 catalyst. The reaction is environmentally friendly (O2 oxidant) and proceeds at room temperature under visible-light irradiation of wide-ranging wavelength (see picture: x=conversion of CH3CHO into CO2, A=absorbance).
