Hydrogen sulfide (H₂S) is a toxic and corrosive substance that is either naturally in aqueous or gas form or can be generated by industrial processes (e.g., in the petroleum industry). Globally, H₂S production (from both petroleum and natural sources) has reached 10 million tons annually, which will increase further. Using H₂S sources as feedstock for H₂ generation is a promising approach for eliminating H₂S and producing clean energy. The thermal decomposition of H₂S could be attractive from an economic standpoint. However, this process has several challenges, including thermodynamic limitations (high operating temperature, equilibrium limitation, and low conversion rate). Catalytic decomposition of H₂S for H₂ generation has drawn significant attention as an alternative process for H₂ generation at lower operating temperatures.
We aim to develop, synthesize, characterize, and test innovative catalysts with promoted lifetime, activity, and selectivity for H₂ generation via the thermo-catalytic decomposition of hydrogen sulfide (H₂S).
