제목 Scalable and Concurrent Generation of Homogeneous Acid Co(III) and Base Co(I) Electrocatalysts Using a Divided Electrolyzer
초록 A scalable and simultaneous synthesis of Co(III) and Co(I) electrocatalysts using an electrolyzer is reported for the first time. The overpotential gain of oxygen evolution reaction (OER) by high acid and hydrogen evolution reaction (HER) by high base was utilized for this new state-of-the art electro-syntheses. Difference in generation rate between acid electrocatalyst Co(III) and base electrocatalyst Co(I) was minimized by controlling the existence of H3O+ ions. Also, variation in the nature of cathode and anode materials was found to influence the formation rate of both acid Co(III) and base Co(I) electrocatalysts. We have shown that by selecting a suitable combination of electrode pair and controlling the presence of H3O+ ions it becomes possible to synthesize 3.5 mM of Co(III) and 2.5 mM of Co(I) simultaneously in both compartments of a divided electrolytic cell. This achievement on the hitherto unreported development in electrocatalyst synthesis strategy is the first of its kind in divided electrolytic cells.
