Interfacial electric field effect on electrochemical carbon dioxide reduction reaction

Defect engineering of two-dimensional materials for advanced energy conversion and storage

“…[316][317][318][319][320][321][322][323][324] From a thermodynamic view, the CO 2 RR is kinetically sluggish with a large overpotential owing to the extremely high stability of CO 2 molecules and multiple electron transfer processes. [325][326][327][328] Therefore, rational electrocatalyst design is necessary to reduce the overpotential and extra energy input for enhanced conversion efficiency.…”

Metal functionalization of two-dimensional nanomaterials for electrochemical carbon dioxide reduction

“…The CO 2 RR basically involves three processes: (1) CO 2 dissolves, diffuses in the electrolyte, and chemically adsorbs on the active site of cathode catalysts; (2) electron transfer and/or proton migration to cleave the C–O bonds and/or generate C–H bonds, followed by the dimerization, trimerization, hydrogenation or dehydration to form different intermediate products; (3) configuration rearrangement of products and their desorption from the electrode surfaces. 26,29–31 There is no doubt that the second process is critically important and involves complex reactions with multiple steps.…”

Interfacial Electric Field Tuning Carbon-Catalyzed Persulfate Activation toward a Maneuverable Oxidation Pathway for Enhanced Removal of Bisphenol A

“…Utilizing electric fields has been demonstrated to be a clean and efficacious approach to manipulate the thermodynamics and selectivity of chemical reactions. − With the presence of an electric field, the bond structures and molecular geometries of the reactants and even the transition states can be altered due to the field-dipole interactions, thus affecting the outcomes of a reaction. − Undoubtedly, the electric field is also anticipated to influence the homogeneous/heterogeneous catalytic reactions. − For example, the NO decomposition over Pt catalyst, the epoxide rearrangement over Al 2 O 3 catalyst, and the electroreduction of CO 2 over Re-bpy catalyst were reported to be remarkably boosted with the applying of external electric fields. ,, The internal electric field induced by the piezoelectric effect can promote the catalytic persulfate activation over Fe-doped MoS 2 nanosheets . There are several ways to artificially produce large electric fields to change the chemical reactions, involving the field emission microscope, scanning tunneling microscope, the electrode/electrolyte interface in an electrochemical cell (called as interfacial electric field, IEF), and so forth. ,, Among them, exploiting the IEF is a relatively easy way to study the electric field effect on chemistry . When a polarized electrode is immersed into the electrolyte solution, the oppositely charged species in the solution would be adsorbed onto the surface of the electrode, forming a double layer with an IEF.…”
