摘　　要：Three binuclear metal (M=Co,Fe,Mn) xanthine bridged bis-corrole complexes were synthesized and investigated as electrocatalysts for the hydrogen evolution reaction (HER).All the prepared metal bis-corrole catalysts exhibited good HER performance when using acetic acid (AcOH);trifluoroacetic acid (TFA);p-toluenesulfonic acid (TsOH) as proton sources.The catalytic HER activities followed an order of Co bis-corrole (1)> Fe bis-corrole (2)> Mn bis-corrole (3);complex 1 exhibited a significantly lower overpotential at -270 mV (in TsOH).Furthermore,complex 1 may go EECC and EECEC pathways in organic solvents (E: electron transfer step,C: proton coupling);exhibit an HER activity with a turnover frequency (TOF) of 85 h^(-1) and a Faraday efficiency of 94% when using water as proton source.
