Electrocatalytic amino acid synthesis from biomass-derivable keto acids over ball milled carbon nanotubes

“…25–31 As an example, electrocatalytic reductive amination (ERA), occurring via the pathway shown in Scheme 1, has several advantages. Similar to other well studied electrocatalytic reactions including CO 2 /CO reduction, 32–36 N 2 reduction 37–40 and O 2 reduction 41–43 reactions, it proceeds under environmentally benign conditions, using electrons as reductants and water as the hydrogen source. Additionally, the selectivity of ERA can be facilely controlled by altering the applied potentials.…”

Perspectives on Carbon-Based Catalysts for the Two-Electron Oxygen Reduction Reaction for Electrochemical Synthesis of Hydrogen Peroxide: A Minireview

“…64 In addition, the surface functionalization of the electrode and the design of the reactors are also important. 65,66 It has been demonstrated that the reaction rate of 2e − -ORR can be significantly enhanced upon partially hydrophobic treatment of the electrode surface. 67−69 Moreover, in addition to designing and synthesizing highly selective active sites, it is equally important to increase the density of active sites at the reaction interface.…”

In addition, the surface functionalization of the electrode and the design of the reactors are also important. , It has been demonstrated that the reaction rate of 2e – -ORR can be significantly enhanced upon partially hydrophobic treatment of the electrode surface. − …”

Low-cell-voltage electrosynthesis of hydrogen peroxide

“…However, there is less research on the overall electrochemical process, including the ORR, OER, and ionic conduction, which is particularly important to the efficiency and energy consumption of H 2 O 2 production. 12,13 Typically, H 2 O 2 electrosynthesis can be achieved via flow cell reactors with a high current density to explore the practicality of H 2 O 2 production using an electrochemical method. 9 Cell voltage is a crucial parameter that affects the energy consumption of the electrochemical process.…”
