Porous Materials for Electrocatalytic Oxygen Reduction Reaction

Porous materials have been widely studied as oxygen reaction reduction (ORR) catalysts since they have large surface areas and abundant pore channels, which effectively enhance mass transport and provide accessible active sites in electrocatalytic reactions. In this chapter, the recent research on porous materials, including the fabrication strategies and application in ORR catalysts, is summarized. Selected examples provide insights into the structural–performance relationships between porous structures and ORR performance.
