Cu/Cu x S‐Embedded N,S‐Doped Porous Carbon Derived in Situ from a MOF Designed for Efficient Catalysis

The reasonable design of the precursor of a carbon‐based nanocatalyst is an important pathway to improve catalytic performance. In this study, a simple solvothermal method was used to synthesize [Cu(TPT)(2,5‐tdc)] ⋅ 2H 2 O (Cu‐MOF), which contains N and S atoms, in one step. Further in‐situ carbonization of the Cu‐MOF as the precursor was used to synthesize Cu/Cu x S‐embedded N,S‐doped porous carbon (Cu/Cu x S/NSC) composites. The catalytic activities of the prepared Cu/Cu x S/NSC were investigated through catalytic reduction of 4‐nitrophenol (4‐NP) to 4‐aminophenol (4‐AP). The results show that the designed Cu/Cu x S/NSC has exceptional catalytic activity and recycling stability, with a reaction rate constant of 0.0256 s −1 , and the conversion rate still exceeds 90 % after 15 cycles. Meanwhile, the efficient catalytic reduction of dyes (CR, MO, MB and RhB) confirmed its versatility. Finally, the active sites of the Cu/Cu x S/NSC catalysts were analyzed, and a possible multicomponent synergistic catalytic mechanism was proposed.
