Preparation and Electrochemical Properties of Poly(Ionic Liquid)/Melamine Carbon-Based Materials
Melamine and poly[3-cyanomethyl-1-vinylimidazole bis(trifluoromethanesulfonyl)imide](PCMVImTf2N)were in-situ compounded with different mass ratios as precursors,and calcined at high temperature to prepare a porous carbon-based catalyst.The experimental results showed when the mass ratio of melamine to PCMVImTf2N was 1:7,the prepared carbon material NC-7 exhibited excellent electrocatalytic hydrogen evolution ability in 0.5 mol/L sulfuric acid(H2SO4)electrolyte.When the current density was 10 mA/cm2,the overpotential was 117 mV,and the corresponding Tafel slope was 46 mV/dec,the performance was better than those of many metal-free electrocatalysts.
