Core Shell 001‐TiO 2 @APF Heterojunction Photocatalysts for Enhanced Water Treatment Performance

ABSTRACT The efficient separation and transfer of photogenerated charge carriers remain a difficult challenge in photocatalysis. While the heterojunctions are an effective strategy for promoting photogenerated charge separation, inefficient migration at the interface often hinders the development. Herein, we report a core‐shell organic‐inorganic hybrid system, TiO 2 @3‐aminophenol formaldehyde resin spheres (001‐TiO 2 @APF) for photocatalytic water treatment. The 001‐TiO 2 @APF heterojunction achieves a 100% degradation efficiency of glyphosate in 6 h with a reaction rate constant of 0. 0068 min −1, which is 6. 2 times that of APF (0. 0011 min −1) and 1. 3 times that of bare TiO 2 (0. 0051 min −1). XPS analysis confirms the formation of Ti‐O‐C covalent bonds at the organic‐inorganic interface, which effectively addresses the charge transport challenge and facilitates rapid carrier migration across the heterojunction. This work underscores the importance of atomic‐level interfacial engineering in constructing high‐efficiency inorganic‐organic photocatalysts for sustainable water purification.
