On water reaction
WebWater electrolysis consists of two half-reactions; the hydrogen evolution reaction (HER) on the cathode and the oxygen evolution reaction (OER) on the anode. Under alkaline conditions, the slow and complex four-electron transfer process of the OER has been fully emphasized in academia as well as industry, which has promoted the development of a … WebWater is a desirable solvent for chemical reactions for reasons of cost, safety, and environmental concerns, and the study of organic reactions in aqueous solvents has an …
