Noble Metal-Free Electrocatalysts for Energy Applications

Abstract

There has been a great deal of interest in the development of electrocatalysts for energy applications that are based on materials that do not contain noble metals. Transition metal oxides, nitrides, carbides, phosphides, and chalcogenides are the primary classes of non-noble metal-based electrocatalysts. In this chapter, a compilation of the developments in the field of noble metal-free electrocatalysts for oxygen evolution reactions and hydrogen evolution reactions has been highlighted. These developments consider several optimization strategies for improving catalytic behavior and realizing effective electrocatalysis.
