Oxygen evolution reaction (OER) is a 4-electron process which takes place at the anode, in an electrolysis cell (2, 3). Compared to HER, the OER process has more sluggish kinetics, where M represents surface active sites of the catalysts and M–OOH, M–O and M–OH are the adsorption intermediates of each … Zobacz więcej Water electrolysis, is an endergonic reaction that requires a theoretical amount of ΔG0 = + 237 kJ mol−1 of electrical energy (Gibbs free energy of the reaction) to be applied at standard conditions for 1 mol of water to … Zobacz więcej In order to evaluate catalyst performance for the OER certain electrochemical and spectroscopic techniques are used to acquire information on the activity, stability and faradaic … Zobacz więcej Witrynaimpurity is shown in Figure 2 versus impurity content. At low impurity concentration (x = 0.01 to x = 0.03 for Fe and to x = 0.02 for Co) we got a negligible cell magnetization. At such low concentrations Co and Fe are non-magnetic. The average magnetization of im-purities versus impurity content is shown in Figure 3. As was discussed in our ...
