The water-splitting potential consists of the thermodynamic potential, cathode/anode overpotential, and the reaction ohmic drop (Equation 1.6).E=E0+Z1+|Z2|+iRwhere E refers to the work voltage driving the reaction of water electrolysis, E0 is the thermodynamically potential of water electrolysis ...
38) oxides/(oxy)hydroxides by employing X-ray absorption spectroscopy (XAS), especially operando XAS measured during electrolysis of a catalyst at a preset applied potential. The results obtained from these significant studies provided some crucial information for understanding the origin of high ...
electrocatalytic water splitting has become a research hotspot for large-scale hydrogen production2. The hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) are the two half reactions
The electrolysis was carried out with a constant oxidation current of 1 mA for 60 min. A measure of 500 μl of the gas sample in the compartment containing the working electrode was transferred by a specific syringe to the gas chromatography, (Shimadzu) where the amount of O2 ...
