报告摘要
Integrating the reverse water gas shift reaction (H₂ + CO₂ → CO + H₂O) with catalytic carbonylation is an effective pathway to convert CO₂ into value-added chemicals such as alcohol, amine and carboxylic acid.
The heterobimetallic ruthenium–cobalt catalytic system exhibited good catalytic performance and reusability in the reductive alkoxycarbonylation of olefins with carbon dioxide. Compared to the previous system only consisting of ruthenium catalyst, the binary catalyst system effectively reduced the usage of noble metal and ionic liquid additives. The respective contribution of ruthenium and cobalt catalysts in this multiple-step catalytic process was investigated by a series of condition-controlled experiments. The evolution of the ruthenium catalyst and the occurrence of alkene hydrogenation during the reaction was explained by theortical calculations.
The acid-aid heterobimetallic ruthenium-cobalt catalytic system for the reductive hydroformylation with carbon dioxide was established. Various alkenes, including the wastes from biomass and petroleum industry, could be upgraded to valuable alcohols with this protocol. Acid promoted reverse water-gas shift (RWGS), thereby accelerating the hydroformylative synthesis of alcohol. The theoretical computations revealed that acid promoted RWGS by facilitating the dehydroxylation of ruthenium hydroxycarbonyl intermediate.
