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 … On-water reactions are a group of organic reactions that take place as an emulsion in water and have an unusual reaction rate acceleration compared with (i) the same reaction in an organic solvent, or (ii) the corresponding dry media reaction. This effect has been known for many years but in 2005 … Ver mais In one study a coupling reaction between an indole and a quinone takes place at room temperature without catalyst in water in 82% chemical yield even though reactants and products are insoluble in this medium.
