Hydrogen Electrode Reaction on Electrocatalytically Active Metals

Improve Electrochemical Hydrogen Insertion on the Carbon Materials Loaded with Pt nano-particles through H spillover

“…There are several steps involved in hydrogen spillover: H generation from H 2 O molecules and subsequent electro-sorption on the Pt surface, H spillover onto the carbon surface, H surface diffusion and insertion in the carbon nano structure. The Pt catalyzed HER has been extensively studied [30][31][32][33]. HER overpotential can be substantially reduced on Pt catalyst surface, so does the potential for H UPD.…”

Numerical simulation of diffusivity of hydrogen in thin tubular metallic membranes affected by self-stresses

“…This means that we can obtain an ADC value close to the SFDC by this method. In experiments [1,2,[13][14][15][16], the hydrogen electrode reaction is along the fast Volmer-slow Tafel mechanism on Pd surface and j0 is the same as the applied current while it is small [34]. On the other hand, the assumption of large volume V in Eqs.…”

“…The actual metal (alloy) surface and bulk processes are complex [11,[32][33][34][35], for example, surface reactions (e.g. the Tafel and Heyrovsky steps) at electrode will diminish the permeation ux during hydrogen absorption [11].…”

Catalytic reduction of vat and sulfur dyes with hydrogen

“…The explanation for the different behaviour of vat and sulfur dyes towards the same reducing agent comes from previous literature on the electrolytic hydrogenation of organic substances (Enyo 1983). It is indeed demonstrated that, at cathodes catalysing the hydrogen evolution reaction, the reduction pathway by transfer of either hydrogen atoms or electrons depends on the organic function engaged in the process.…”
