Carbon Emissions, Electrocatalysts, Fossil fuels, Green Hydrogen, Transition Metal DichalcogenidesAbstract
The world aims to reduce carbon emissions by transition to alternative and renewable energy sources such as green hydrogen, which is cleaner and more sustainable for various applications compares to the traditional fossil fuels. Electrocatalytic splitting of water is one of the best promising method for hydrogen production due to its affordability, sustainability, and eco-friendliness. Transition metal dichalcogenides (TMDs) have emerged as the essential electrocatalysts for this process. This paper presents a review on the progress in TMDs as electrocatalysts. It starts with a concise discussion on the overview of TMDs and their unique properties that made them attractive in the electrocatalysis of water. However, various descriptors of a good electrocatalyst were elaborated as well as some of the ways of improving the catalytic activity of the existing TMDs-based electrocatalysts. The methods of synthesis of the TMDs-based electrocatalysts were also explored. The paper concludes by pointing out some of the challenges that hinder the progress of the field and future directions that will greatly contribute toward improving the entire field of electrocatalytic splitting of water for effective hydrogen generation.
