Catalytic Performances of Ni-containing Mesoporous TUD-1 Catalysts in Steam Reforming of Acetic Acid

Novel coke-resistant Ni-containing TUD-1 supported catalysts were successfully synthesized for the steam reforming of biomass-derived acetic acid. The catalysts exhibited exceptional catalytic activity, coupled with remarkable stability. Rigorous characterization through XRD, N2 adsorption–desorption, ICP-MS, and Pyridine-DRIFT analyses provided valuable insights into their structural and physical features. The investigation focused on the effects of diverse preparation methods and reaction temperatures on hydrogen selectivity, with a meticulous comparison of the one-pot hydrothermal synthesis and impregnation techniques. Catalytic activity measurements at various temperatures revealed a captivating trend: lower temperatures yielded superior hydrogen selectivity, underscoring the pivotal role of temperature in steering the desired reaction pathway. Notably, the catalysts synthesized via the one-pot hydrothermal method exhibited remarkable hydrogen selectivity and stability. Their outstanding performance promises substantial advancements in the field. Moreover, the catalysts displayed exceptional endurance during the steam reforming of acetic acid, sustaining their activity for a minimum of 12 h, signifying their potential for long-term applications. These findings hold great promise for the development of efficient and durable catalyst systems, contributing to the progression of sustainable hydrogen production from biomass sources.
