| Abstract: | In this review, the environmental issues and the energy crisis caused due to overuse of diminishing fossil fuels have been introduced and discussed. The need for new renewable, non-carbon emission energy sources and the importance of hydrogen (H2) as clean and efficient energy generated via hydrogen evolution reaction (HER) through electrochemical water splitting is discussed. The role of an efficient electrocatalyst for HER has been highlighted. The requirement of low-cost, efficient, and durable electrocatalysts for HER to replace the costly platinum (Pt) electrocatalysts is introduced. The importance of nano transition metal carbides (TMCs), especially molybdenum carbide (Mo2C), as an efficient and stable electrocatalyst has been discussed in detail. The progress and advances to improve the electrocatalytic performance of nano Mo2C on the basis of synthesis, size, shape, and carbon support in different forms have been presented. The role of different carbon species over Mo2C on HER activity has been discussed. The importance of nitrogen (N) doping within the carbon structure encapsulating Mo2C particles to improve the HER activity has been highlighted. The importance of in-situ developed surface carbon over Mo2C has been discussed in detail. The utilization of waste carbon materials to address the environmental issues caused due to non-biodegradable wastes is also discussed. In the end, the future scope has been highlighted to commercialize Mo2C as a low-cost electrocatalyst for hydrogen production through HER. |
