Macrocyclic butterfly iron cluster complexes: electrochemical investigations

Mononuclear nickel(ii) complexes as electrocatalysts in hydrogen evolution reactions: effects of alkyl side chain lengths

“…Therefore, alternatives are being investigated with much cheaper earth-abundant metals as the catalyst. There are reports of different transition metal complexes 3 with Fe, 4 Mn, 5 Cu, 6 Co 7 and Ni 8 as electrocatalysts for HERs. Various compounds of nickel and cobalt have also been used as the electrocatalysts for water splitting, hydrogen generation, and carbon dioxide reduction, showing their efficient role as electrocatalysts.…”
