Reaction of oxygen with water
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 ... WebIn electrocatalysis, layered double hydroxide (LDH) materials have attracted considerable interest in promoting the oxygen evolution reaction (OER). For the hydrogen evolution …
