摘要：

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).
