New chlor-alkali activated cathodes

Syngas production from electrochemical reduction of CO2: current status and prospective implementation

“…During the last few decade, several elements, such as Cu, Au, Pd, Rh, Fe and Mo, [63][64][65] Ni, [66][67][68] Ru, 69,70 and Co, 71 have been investigated with the aim of finding a suitable replacement for Pt that would be the most active H2 evolution catalysts. Because of the promising results that have recently been achieved, HER catalysts based on earth abundant elements, such as Co, Fe, and Ni, have been at the centre of the attention in current research.…”

Investigation of the surface properties and the hydrogen evolution reaction, HER, at thermal rhodium oxide electrodes

“…While an enormous amount of reports on the HER at a wide variety of electrode materials is available in the open literature, the number of papers investigating the cathodic behaviour of metal oxides is rather scarce [4][5][6][7][8][9][10][11][12][13][14]. A possible reason for this is that these materials are in principle thermodynamically unstable in the hydrogen evolution potential region [15].…”

Copper-Doped Cobalt Spinel Electrocatalysts Supported on Activated Carbon for Hydrogen Evolution Reaction

“…Therefore, the development of alternative non-noble metal electrocatalysts based on abundant and low-cost materials has attracted considerable attention to efficiently scale up the production of hydrogen. In order to obtain an efficient electrocatalyst towards HER, several specific properties are desirable, such as low hydrogen overpotential, no potential drift with time, good chemical and electrochemical stability, high adhesion to the support, high tolerance to poisoning by impurities, no environmental problems in the manufacturing process, and straightforward preparation at a low cost/lifetime ratio [5].…”
