Effect of ethylenediaminetetraacetic acid (Rowland`s effect) on electrochemical behavior of transition metals and electrocatalysis of hydrogen evolution reaction: Rowland`s effect on noble metals
- Trondheim Univ. (Norway)
Rowland`s effect, which is due to a surface treatment in the presence of ethylenediaminetetraacetic acid (EDTA), is studied by cyclic voltammetry on Pt, Pd, Ru, Rh, Ir, Au, and Re electrodes. In general, the treatment causes the destruction and removal of oxides from the surface of metallic substrates resulting in the subsequent increase in the working surface area and its depassivation. Rowland`s effect is of great importance for electrocatalysis of hydrogen evolution and oxygen reduction as well as for surface pretreatment of substrates and catalytic coatings (Raney nickel, composite Raney alloys, and other catalysts) leading to an enhanced contact between the substrate and the catalytic coating.
