Microorganisms exhibiting electrocatalytic activity have the potential to generate reducing equivalents (protons and electrons) through their metabolic reactions and transport them to an external electron acceptor [1]. This electrocatalytic activity of a biocatalyst is the basis for the development of ...

This work covers the critical role of the triple-phase boundary of CO2, protons, and electrons in CO2 conversion. Proton and electron conduction in electrocatalysts are discussed as composite materials and single-phase materials, respectively. Relatively established composite proton- and electron-...
Answer to: The mass number of an atom depends primarily on the number of a. protons and neutrons. b. positrons. c. neutrons and electrons. d...
Electrocatalytic CO2 reduction at near-ambient temperatures requires a complex inventory of protons, hydroxyls, carbonate ions and alkali-metal ions at the cathode and anode to be managed, necessitating the use of ion-selective membranes to regulate pH. Anion-exchange membranes provide an alkaline ...
