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 compounds (VOCs). Here, a facile in situ modulation protocol developed could enable the growth MOx (M = Ti, Zn, W, Ce) with oxygen vacancy (Ov) on –NH2-functionalized COF surfaces construct NH2–COF/Ov–MOx Z–scheme heterojunctions stability efficiency (98.3 %) photo-oxidation formaldehyde, acetaldehyde, acetone. The –NH2 functionalization enhanced VOC chemisorption via H-bond interaction. Moreover, constructed fast charge transfer channel (Ov–M–N) at interface not only promoted directional migration photo-excited carrier, activated adsorbed O2 H2O quickly •OH, but also effectively inhibited injurant formation realize precise control conversion path. These findings offer new insights into customizing interfacial structure indoor air purification.

Abstract Formaldehyde (HCHO), a common pollutant in industrial productions and indoor environments, poses health risks to humans. Thermal catalytic oxidation has been regarded as an effective approach eliminate formaldehyde pollution due its environmental benefits operational convenience. In this study, Pd‐based catalyst with high dispersion of Pd was prepared by facile impregnation method choosing the appropriate calcination temperature MgFe 2 O 4 support, which demonstrated excellent activity robustness during long term test 60 h conducted at 30 °C WHSV 30,000 mL/(g‐h). A comprehensive set characterizations, such N physisorption, CO chemisorption, STEM, XRD, XPS, H ‐TPR, ‐TPD, were employed. The results revealed that outstanding stability resulted from Pd, good oxygen mobility, strong antioxidant capacity low desorption temperature, amount temperature. This study presents palladium significant application potential removal.
