Hydrogen evolution reaction enhanced by water-soluble metallopyridinoporphyrazine complex adsorbed on highly oriented pyrolytic graphite
Original language description
The ultrathin (∼2 nm) film of N,N',N'′,N′″-tetramethyltetra-3,4-pyridino-porphyrazinato-cobalt(II) complex adsorbed on the basal plane of highly oriented pyrolytic graphite (HOPG/Co(I)Tmtppa) was used as a mediator for electrocatalytic hydrogen evolution reaction (HER) in a wide range of pH. The Co(I)Tmtppa film was characterized by in-situ backscattering spectroscopy, atomic force microscopy and cyclic voltammetry. Electrocatalytic measurements of HOPG/Co(I)Tmtppa electrode using voltammetric techniques showed up to 60-fold increase of current density and overpotential decreased by 300 mV, compared to the bare HOPG electrode at pH 11 and confirmed very good stability with only 8% deviation over 1000 cycles. The Tafel analysis indicated the Volmer-Heyrovsky mechanism of hydrogen evolution reaction with hydrogen adsorption rate-determining step at all pH values.
