Oxygen Vacancies Promoted the Selective Photocatalytic Removal of NO with Blue TiO₂ via Simultaneous Molecular Oxygen Activation and Photogenerated Hole Annihilation

Abstract

byproduct formation, resulting in the highly selective removal of NO. This study reveals the dual functions of OVs in defective photocatalysts and also provides fundamental guidance for the selective purification of NO with photocatalytic technology.
