Efficient one-pot synthesis of ruthenium catalysts and their role in optimizing sugar alcohol production: Investigating structural sensitivityOA
The study explores the feasibility of producing ruthenium catalysts supported on char through a one-pot synthesis,an original approach for the preparation of noble metal-based catalysts in this field.This method combines high-temperature stages,such as catalytic support carburization and catalyst activation,in a single step.The innovation represents a significant advancement in utilizing cellulose as a model of waste biomass,enhancing its value,and reducing catalyst production costs.The one-pot catalysts were successfully tested in the hydrogenation reaction of sugar mixtures(L-Arabinose and D-Galactose)under mild conditions,achieving full selectivities.The research also introduces for the first time in that reaction a structural sensitivity analysis of the reaction,comparing experimental results with a theoretical model.The findings reveal a direct correlation between catalytic activity and the{0001}exposed face of hcp ruthenium nanoclusters.This discovery opens new avenues for industrial-scale catalyst development,promising substantial reductions in energy and production costs,and emphasizing the economic appeal of the process.
