The reasonable design of the precursor of the carbon-based nanocatalyst is an important pathway to improve its catalytic performance. In this study, a simple solvothermal method was used to synthesize [Cu(TPT)(2,5-tdc)]·2H 2 O ( Cu-MOF ) containing 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 recycle stability, showing the reaction rate constant is 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 multi-component synergistic catalytic mechanism was proposed.
