Covalent organic frameworks (COF) based materials have exhibited excellent gas and visible light absorption capability, yet are very difficult to generate strong oxidative species for photocatalytic mineralization of volatile organic compounds (VOCs). Here, a facile in situ modulation protocol developed could enable the growth of MO_x (M = Ti, Zn, W, Ce) with oxygen vacancy (Ov) on –NH₂-functionalized COF surfaces to construct NH₂–COF/Ov–MO_x Z–scheme heterojunctions of excellent stability and efficiency (98.3 %) in photo-oxidation of formaldehyde, acetaldehyde, and acetone. The –NH₂ functionalization enhanced VOC chemisorption via H-bond interaction. Moreover, the constructed fast charge transfer channel (Ov–M–N) at the interface not only promoted directional migration of photo-excited carrier, activated adsorbed O₂ and H₂O to quickly generate strong •OH, but also effectively inhibited injurant formation to realize the precise control of the conversion path. These findings offer new insights into customizing the interfacial structure of COF for indoor air purification.
