主　　题：Sb_(2)WO_(6) BiOBr Photocatalytic NO removal S-scheme 

摘      要：Photocatalysis technology is an efficient method for removing nitrogen oxides at low ***,dimension-matched Sb_(2)WO_(6)/BiOBr photocatalysts were synthesized at room temperature via precipitation-deposition *** visible light irradiation,the as-obtained Sb_(2)WO_(6)/Bi OBr photocatalysts showed enhanced photocatalytic performance compare with the pure Sb_(2)WO_(6) and BiOBr for removal of *** optimal ratio for photocatalytic performance of Sb_(2)WO_(6)/BiOBr composite was found to be 30 wt.%of Sb_(2)WO_(6),which showed excellent recycling property even after 5 ***,in situ DRIFT was carried out to reveal the time-dependent evolution of reaction intermediates during photocatalytic NO *** probable photocatalytic mechanism was considered based on the active species capture *** enhanced photocatalytic performance for the Sb_(2)WO_(6)/BiOBr composite photocatalyst perhaps is attributed to the interaction between BiOBr and Sb2WO6 and S-scheme charge transfer path.
