Formate dehydrogenase - Wikipedia

WebThe generation of formate from CO 2 provides a method for sequestration of this greenhouse gas as well as the production of a valuable commodity chemical and stabilized form of hydrogen fuel. Formate dehydrogenases are enzymes with the potential to catalyze this reaction; however they generally favor the reverse process, i.e., formate oxidation. WebBased on electrochemical and spectroscopic experiments, including data for a new [Ni (P Cy2 N PhOMe2) 2 (CH 3 CN)] 2+ complex, we propose a mechanism in which the rate-determining step is a proton transfer from the Ni–O 2 CH β-H to the ligand pendant base coupled with a 2e − transfer to Ni ( II ), circumventing direct hydride transfer to the metal. corn flakes with peanut butter treatWebApr 12, 2024 · Electro-oxidation of glycerol on Ni3S2 gives high yields of formate.
