Optimization of Tungsten Carbide/MOF Hybrids as Electrochemical Water Splitting Catalysts for HER

Abstract

The depletion of traditional energy supplies, that is, fossil fuels, has increased interest in hydrogen as a source of clean energy. As a fuel, hydrogen boasts a high energy density, carbon-free byproducts, and the ability to be stored. Water splitting is a carbon-neutral method for the sustainable creation of hydrogen. However, the process requires highperformance, stable, and inexpensive catalysts for kinetic and economic viability. Diverse catalysts have been investigated for the effective production of hydrogen through the water splitting process. At operationally relevant current densities, tungsten carbide is a resilient and electrochemically active material with low Tafel slopes and overpotentials equivalent to the standard catalyst platinum. This thesis is to describe the advances that Tungsten carbide and its hybrids have achieved in water-splitting. Particular focus has been given to popular techniques that can enhance the catalytic capabilities of the hybrids for the whole process, beginning with the synthesis procedures and their influence on the structure and properties. In order to determine the optimal class of materials in accordance with hydrogen production procedures, a significant insight into future considerations for catalytic enhancement is also provided for researchers and industry alike.
