▎ 摘　　要

NOVELTY - Conjugated polymer composite material is formed by compounding a metal porphyrin coordination polymer layer and carbon material layer, where the carbon material layer is formed by carbon material with large conjugated system. The metal porphyrin coordination polymer layer is formed by an organic ligand with a plane conjugated structure and ruthenium ion (Ru3+) coordination formation. The feeding ratio of the metal coordination polymer layer to the carbon material layer is 1:8-2:1 by weight, and molar ratio of Ru3+ in the metal coordination polymer layer to the organic ligand is 2:1. USE - Conjugated polymer composite material used as hydrogen evolution reaction electrocatalyst (claimed) and in electrode material for hydrogen evolution reactions. ADVANTAGE - The composite material exhibits a stronger alkaline HER catalytic activity than the current most advanced Pt/C,shows better stability, and has good application prospect, and is cost-effective. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: Method for preparing a composite material, which involves: (1) mixing organic ligand, carbon material, surfactant and acid into a solution A, and obtaining trivalent salt of Ru3+ into solution B; and (2) mixing the solution A and the solution B for reaction, and separating a solid product to obtain the catalyst. Electrode material for hydrogen evolution reactions, which comprises composite material and Nafion (RTM: Sulfonated tetrafluoroethylene).
