Review: Recent Developments in Electrode Materials for Oxygen Reduction Reaction

Oxygen reduction reaction (ORR) has primary role in energy devices including green energy, light weight and low-cost alternative electrode materials. Recently, number of efforts was made to synthesis highly active electrode catalyst for energy harvesting and energy demands. The electrode catalysts have attracted much attention due to their physical and chemical properties. In this review, we mainly focused on different preparation methods developed for the production of different kinds of electrode materials, which could apply for ORR in fuel cell applications. The electrode materials such as nanoparticles, bimetallic, metal oxides, conducting polymers and nanocomposites have been reviewed in this article. Further developments in the fuel cell process will improve the pioneering electrode catalysis to contribute our future renewable some of energy storage devices.
