In practical applications,relative humidity in the air is a key factor affecting the photocatalytic removal of NO,which is often overlooked in previous studies.Here,we developed a direct Z-scheme UiO-66-NH2/Bi2MoO6 heterojunction with a nanoflower-like structure to system-atically investigate the effect of relative humidity on pho-tocatalytic removal of NO.The optimized heterojunction for the removal efficiency of NO was 71.6％at 1.07 mg.m-3 NO concentration(relative humidity=10％),and the generation of NO2 was only 1.1％.Interestingly,with the increase in relative humidity,it showed a higher inhibition effect on NO2,while the removal of NO decreased slightly(8％),which might be attributed to the affinity effect of NO2 with water molecules and the com-petitive adsorption of H2O and NO on the surface of the heterojunction photocatalysts.Furthermore,the reaction pathways of NO removal at the developed heterojunctions were revealed by in situ DRIFTS analysis.This work provides a novel vision for the development of direct Z-scheme heterojunction photocatalysts to effectively remove NO and inhibit the formation of toxic intermediate NO2 under different humidities.
