Recent Developments in Electrocatalysis

Electrocatalysis is the catalytic process involving oxidation and reduction reactions through the direct transfer of electrons between species at the electrochemical interface. An electrocatalyst specifically reduces the overpotential needed to allow the thermodynamically possible reaction to occur faster. These catalysts can be homogeneous, heterogeneous, or microbial in nature. Electrocatalysts are used in a wide range of fields, including corrosion, wastewater treatment, and energy storage. These promising applications will all be critical to a more sustainable energy future. The articles in the current issue of Interface look at this question of designing and using novel electrocatalysts from several different angles.
