Electrocatalysis

Definition

Electrocatalysis is a type of catalysis that results in the modification of the rate of an electrochemical reaction occurring on an electrode surface. The relative electrocatalytic properties of a group of materials at a given temperature and concentration are not necessarily constant, and may vary according to the different dependence of rates on electrical potential.

    Identifying trends in electrocatalytic activity for carbon dioxide reduction can help with catalyst design, but are difficult to define. Here, the authors develop an electrochemical kinetic model of the process, identifying scaling relations relating transition state energies to CO adsorption energy on metal surfaces.

    The surface oxygen storage capacity is an important metric of catalytic activity, but its dependence on strain is not well characterized. Here, the authors show the surface oxygen nonstoichiometry in coherently strained CeO2-δ films increases non-monotonically with biaxial strain.

    In water-alkali electrolyzers, sluggish water dissociation kinetics on platinum-free electrocatalysts result in poor hydrogen-production activities. Here the authors report a MoNi4 electrocatalyst which reduces the kinetic energy barrier of water dissociation, leading to improved hydrogen-production performance.

    Homogenous transition metal electrocatalysts are topical owing to their role in processing electrical energy and mediating the synthesis of chemical fuels. Mechanisms can be uncovered using electrochemical techniques and data analyses, along with complementary spectroscopic techniques. This Review presents case studies highlighting the utility of these methods in the context of electrocatalysis for chemical fuel production.
