Abstract

Transition metal-nitrogen co-doped carbon materials are a kind of high efficiency electrocatalysts for CO2 reduction. The nitrogen-doped carbon material prepared by pyrolysis polymer was used as the support,and the nickel precursor was synthesized by an impregnation method.The highly dispersed Ni-N-C type catalysts(Ni/NC) were obtained through the photochemical method with the assistant of infrared lamp for 2 h.The morphology,structure,phase and composition of catalysts were characterized by scanning electron microscopy(SEM),gas physisorption,X-ray diffraction(XRD) and X-ray photoelectron spectroscopy(XPS).The electrocatalytic activity on CO2 reduction reaction was analyzed.The electrochemical performance test results showed that with the electrolyte(KHCO 3) of 0.5 mol/L,the sample with Ni loading of 2% delivered the best catalytic performance and CO partial current density was significanted improved.,the Tafel slope was 492 mV/dec,and the initial overpotential was 286 mV.At -0.6 V(vs.RHE),the Faradaic efficiency of CO was 78%.The ratio of 0.5~3.6 for n(CO)/n(H2) was achieved in the range of -1.0~ -0.5 V(vs.RHE).
