A new metal-free xanthene-bridged bis-corrole had been synthesized and used as a catalyst for electrocatalytic hydrogen evolution reaction for the first time. This bis-corrole demonstrated high catalytic efficiency in DMF and acetonitrile-aqueous solution upon using acetic acid as the protons source. The turnover frequency (TOF) could reach 627.75 h –1 in DMF at the overpotential of 924 mV and 581.42 h –1 in neutral buffer acetonitrile-aqueous solution at the overpotential of 828 mV. The prepared bis-corrole also exhibted good stability in the electrolysis. This study highlights that linking one corrole macrocycle to another can lead to the metal-free bis-corrole as a stable HER catalyst.
