Photocatalytic technology provides an effective strategy for aerobic purification of dilute gaseous NO pollutant, but suffers from its low efficiency. In this study, we demonstrate that the bicomponent Au/CeO2 photocatalyst possesses an enhanced photocatalytic NO removal performance under visible light irradiation, with a higher NO conversion efficiency (65%) and triple rate constant (0.1451 min−1) versus CeO2 (50%, 0.0448 min−1). Density function theory calculations and experimental results revealed that oxygen vacancies on the CeO2 componen...
