D2o reaction
WebHydrogen–deuterium exchange (also called H–D or H/D exchange) is a chemical reaction in which a covalently bonded hydrogen atom is replaced by a deuterium atom, or … WebABSTRACT 1605331 Brankovic, Stanko R. The study examines the effects of positive strain in platinum (Pt) and palladium (Pd) monolayer catalysts on the efficiency of electrolytic hydrogen isotope separation in applications such as separation of heavy, deuterated water (D2O) from normal H2O.

Web1 Background. “Heavy water” and “heavy hydrogen” were discovered by Harold C. Urey and co-workers in 1931. Heavy water is the oxide of deuterium, an isotope of hydrogen with one proton and one neutron in its nucleus. At the time of these discoveries, the neutron had not been discovered, thus the name “heavy hydrogen” was used for ...
