The Rowland or EDTA effect on electrochemical behavior of transition metals and in electrocatalysis for the hydrogen evolution reaction. The Rowland effect on some non-noble non-valve transition metals
- Norwegian Inst. of Technology, Trondheim (Norway); and others
The Rowland or EDTA effect for in situ, on situ, and ex situ undermining and cleaning removal of adhering surface oxides from metallic substrates with depassivation and developing as cleaned-up exposed surfaces for hydrogen evolution, has been developed, tested, and presented upon some non-noble non-valve metal (Ni, Fe, Co, Mo, W, Cr, V, Ag) electrodes in alkaline solution. Both achievements, the shift of potentials for hydrogen evolution towards more positive values and the removal of oxide layers were scanned by cyclic voltammetry and indicated by changes in characteristic charge capacity. The method is of substantial importance for the electrocatalytic in situ activation of the hydrogen evolution reaction (HER) and/or oxygen reduction, organic electroreduction and cathodic hydrogenation processes, as well as for preparation of both the substrate surface and particulate catalytic coatings for advanced mutual contacts, one of fundamental questions in electrocatalysis.
