Abstract

"The continuous excessive usage of fossil fuels has resulted in its fast depletion leading to an escalating energy crisis as well as several environmental issues leading to increased research towards sustainable energy conversion. Electrocatalysts play crucial role in the development of numerous novel energy conversion devices including fuel cells and solar fuel generators.

High-efficiency and cost-effective catalysts are required for large-scale implementation of these new devices. Over the last few years transition metal chalcogenides have emerged as highly efficient electrocatalysts for several electrochemical devices such as water splitting, carbon dioxide electroreduction and, solar energy converters. These transition metal chalcogenides exhibit high electrochemical tunability, abundant active sites and superior electrical conductivity. Hence, they have been actively explored for various electrocatalytic activities.

This report details the research on the Carbon dioxide electroreduction and water splitting using metal chalcogenides as electrocatalyst also elaborating on the connection of the composition and the catalytic activity. At first, the aim was to develop catalysts which show desired activity and stability over extended periods. In addition, the catalyst should be economically viable so that it can be produced and applied on an industrial scale. Herein, I have provided comprehensive report of transition-metal chalcogenide electrocatalysts for hydrogen evolution, oxygen evolution, and carbon dioxide reduction and illustrated structure-property correlation that increases their catalytic activity"--Abstract, p. iv
