Review and Outlook of Hydrogen Production through Catalytic Processes

Hydrogen holds immense potential as a sustainable energy source as a result of its eco-friendliness and high energy density. Thus, hydrogen can solve the energy and environmental challenges. However, it is crucial to produce hydrogen using sustainable approaches in a cost-efficient manner. Currently, hydrogen can be produced by utilizing diverse feedstocks, such as natural gas, methane, ammonia, smaller organic molecules (methanol, ethanol, glycerol, and formic acid), biomass, and water. These feedstocks undergo conversion into hydrogen through different catalytic processes, including steam reforming, pyrolysis, catalytic decomposition, gasification, electrolysis, and photo-assisted methods…
