The steps of activating a prospective CO2 hydrogenation catalyst with combined CO2 capture and reduction†
Abstract
Combining CO2 capture and reduction is an efficient strategy to alleviate the high energy requirements for processing CO2 prior to reduction. Catalytic hydrogenation of CO2 captured as alkylcarbonate has previously been reported, but it's ambiguous whether the alkylcarbonate is reduced, as it is in dynamic equilibrium with neutral CO2 in solution. New studies are presented to elucidate the reduction mechanisms of CO2, and CO2 that is captured in solution using a homogeneous ruthenium hydride complex.
