Electrocatalysis

In molecular electrocatalysis, TOF is a kinetic parameter that reflects the catalytic activity and is parametrized by the applied potential. In its most general definition, TOF is the number of moles of product produced per unit time per mole of catalyst contained in thereaction-diffusion layer (not the bulk solution). As noted by Savéant ....

May 29, 2021 · Electrocatalysis is at the heart of many significant chemical transformation processes and advanced clean energy technologies. Traditional noble/transition metal oxides are widely used as electrocatalysts; however, they often suffer from intrinsic disadvantages, including low atom utilization, small surface area, and unfavorable tunability. Fabrication and Applications of Carbon/Clay Mineral Nanocomposites. Bin Mu, Aiqin Wang, in Nanomaterials from Clay Minerals, 2019. 11.4.4.3 Electrocatalysis. Electrocatalysts may participate in electrochemical reactions to increase the oxidation and reduction reaction rate, which is a specific form of catalysts that work at electrode surfaces or the electrode itself. Porphyrin-based frameworks, as specific kinds of metal-organic frameworks (MOFs) and covalent organic frameworks (COFs), have been widely used in energy-related conversion processes, including the oxygen reduction reaction (ORR), oxygen evolution reaction (OER) and CO2 reduction reaction (CO2RR), and also in Small molecule activation, from biocatalysis to artificial catalysis
