:GRQD-NiCo2O4 complexes were prepared by hydrothermal method,the microstructure was analyzed by XRD,SEM and TEM,and the electro-catalytic activity as DMFC anode catalysts was discussed.The microstructure analysis showed that the GRQD-NiCo2O4 complexes were spinel-type structure with NiCo2O4 single phase,and when the concentration of GRQD was higher than 0.25 g/mL,the surface morphology would change the state that GRQD and NiCo2O4 combined with each other.Electrochemical analysis showed that adding GRQD could effectively enhance the conductivity and electrochemical stability of NiCo2O4.When the concentration of GRQD was 0.25 g/mL,the current density of the sample obtained after 500 cycles was about 77.5 A/g,and the remaining current density was the largest(about 69.7%) compared with that after 5 cycles.The sample had the best cost performance as DMFC anode catalyst.
