Hydrogen sulfide (H₂S) is a toxic and corrosive substance that is either naturally present 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 and will continue to increase. Using H₂S sources as feedstock for H₂ generation is a promising approach to eliminate H₂S and produce 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 temperatures, equilibrium limitations, and low conversion rates). 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 catalyst-reactor concepts with enhanced lifetime, activity, and selectivity for H₂ generation via thermocatalytic decomposition of hydrogen sulfide (H₂S) and explore other innovative pathways.
