This review summarizes the performance of electrocatalysts based on two-dimensional graphitic carbon nitride in methanol oxidation reactions. It describes the structure, synthesis methods, and post-synthesis treatments of g-C3N4, and evaluates their performance. Finally, the review discusses the challenges and possible solutions for the future development of DMFC.
Direct methanol fuel cells (DMFC) possess numerous advantages for powering portable mobile devices. However, there are still major challenges in their development and commercialization that originates from the anode catalyst responsible for methanol oxidation reaction. This has motivated researchers to find a cost effective and durable catalyst material for methanol oxidation. Recently, carbon-based 2-D graphitic carbon nitride (g-C3N4) has been found to have good potentials to catalyse alcohol oxidation reactions in fuel cells. This review provides a summarized information of previously developed g-C3N4-containing-electrocatalysts based on the active sites present (e.g., non-metals, noble metals, and non-noble metals) for methanol electro-oxidation to compare their electrocatalytic performance. It also consists of brief examination of their structure, description of different synthesis methods and post-synthesis treatments, and evaluation of their properties that contributes to their resulting performance. The review then concludes with the details of challenges and possible solutions that enable DMFC to be a reliable source of energy in the future. (C) 2021 Hydrogen Energy Publications LLC.
