Photocatalysis technology has been extensively adopted to abate typical air pollutants. Nevertheless, it is a challenge to develop photocatalysts aiming to simultaneously improve photocatalytic selectivity and efficiency. In this study, to improve the photocatalytic selectivity and the performance of (BiO)CO in the oxidation of NO to target products (NO /NO), we developed a novel method to construct La-doped (BiO)CO (La-BOC) for forming localized excess electrons (Ex) on (BiO)CO surface.
