Sulfadiazine (SDZ) pollution can cause genetic mutation of organisms and lead to different kinds of disease for humans, but it is facing the dilemma of low photodegradation efficiency. Different from the traditional photo-catalysts, this work focuses on constructing a multi-electron-channel system in trimetallic metal-organic frameworks (MOFs) to accelerate the separation of electron-hole pairs, in which the carriers can be direction-ally converted among separate electron channels via Fo & BULL;rster resonance energy transfer process. As a result, the optimal trimetallic MOF can sharply remove similar to 70% of SDZ within 20 min and remain unchanged after 9 cycles. These findings provide a new inspiration for designing photogenerated carrier reaction kinetics to accelerate SDZ degradation.
