Abstract The economical consideration of using an electrocatalyst in energy‐related field, composed of non‐precious/sustainable elements is quite noteworthy. In this work, the phosphorus(V) complex of tris‐(pentafluorophenyl)corrole [(TPFC)P V (OH) 2 ] was reported as electrocatalyst for the hydrogen evolution reaction (HER). The electrochemical studies revealed that the HER experienced a ECEC pathway (E: electron transfer step, C: chemical step), and the possible intermediate [P V ]−H species was suggested. (TPFC)P V (OH) 2 displayed excellent HER activity in dimethylformamide (DMF) with trifluoroacetic acid (TFA) as the proton source, and the turnover frequency (TOF) reached 31.75 s −1 at an overpotential of 900 mV. Interestingly, the HER electrocatalytic performance remained extraordinary even applying water as a proton source in acetonitrile/water ( v / v =2 : 3), with a TOF of 18.40 mol mol cat −1 h −1 at an overpotential of 900 mV.
