Designing carbon-based non-precious metal hybrid materials to replace precious metal catalysts to solve environmental pollution problems is a hot topic of research at this stage. In this work, a dual ligand Cu-MOF was synthesized by the solvothermal method and using Cu-MOF as a sacrificial template further vulcanized to obtain Cu1.96S/NSC hybrid material. The morphology and composition of Cu1.96S/NSC hybrid material were investigated by scanning electron microscope (SEM), high-resolution transmission electron microscope (HRTEM), x-ray diffraction (XRD), nitrogen adsorption-desorption, and x-ray photoelectron spectroscopy (XPS) in detail. Cu1.96S/NSC has excellent catalytic activity in the catalytic reduction of 4-nitrophenol (4-NP) to 4-aminophenol (4-AP) showing the reaction rate constant k=0.0242 s-1, which can reach nearly 100% conversion rate in 3 min. Finally, the mechanism of Cu1.96S/NSC hybrid material’s efficient catalytic reduction of 4-NP was deeply explored.
