▎ 摘　　要

NOVELTY - Foam nickel-based composite cathode material of microorganism electrolytic cell comprises a foam nickel substrate and a nano composite catalyst. The nano composite catalyst is uniformly distributed on the foam nickel substrate by adhesive. The adhesive is mixture of nickel nitrate solution and polytetrafluoroethylene turbid liquid. The nano composite catalyst is nano selenium and nano nickel oxide. USE - The foam nickel-based composite cathode material of a microorganism electrolytic cell is useful for recycling energy by microorganisms. ADVANTAGE - The foam nickel-based composite cathode material of a microorganism electrolytic cell has uniform shape, large specific surface area, good electrochemical performance, high porosity, wide aperture controllable range, good fluid transmission performance, stable performance and high mechanical strength, nano-selenium and nano-nickel oxide nano composite catalyst can form micro-mesoporous multi-level pore structure with nickel nitrate in the adhesive thus increases the total surface area, the active site and the hydrogen evolution effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing foam nickel-based composite cathode material of microorganism electrolytic cell using surfactant comprising 60-80 pts. wt. graphene oxide, 60-120 pts. wt. N,N-dimethylformamide and 20-50 pts. wt. nickel-molybdenum alloy and coupling agent, preferably silane coupling agent.
