摘要

The present paper reports an electrochemical study of hydrogen evolution reaction (HER), atcommercially available (Toho-Tenax) nickel-coated carbon fibre (NiCCF) material, in 30 wt.% KOHsolution. Kinetics of the hydrogen evolution reaction at NiCCF were studied for prolonged time, overo the temperature range 22-60 C, where the kinetic parameters were derived by means of a.c. impedancespectroscopy for the cathodic overpotential range: -100 to -500 mV/RHE. The effects of cathodedeactivation (the result of reversible formation of nickel hydride species) upon continuous electrolysisand its reactivation by dissolved molybdenum (introduced to solution in the form of sodiummolybdate) have also been investigated.
