Carbon nanomaterials for metal-free electrocatalysis

Abstract

Carbon materials are continuing in progress to accomplish the requirements of energy conversion and energy storage technologies because of their plenty in nature, high surface area, outstanding electrical properties, and readily obtained from varieties of chemical and natural sources. Recently, carbon-based electrocatalysts have been developed in the quest to replacement of noble metal based catalysts for low cost energy conversion technologies, such as fuel cell, water splitting, and metal-air batteries. Herein, we will present our short overview on recently developed carbon-based electrocatalysts for energy conversion reactions such as oxygen reduction, oxygen evolution, and hydrogen evolution reactions, along with challenges and perspectives in the emerging field of metal-free electrocatalysts.
