“…Jessop P. G. found that CO 2 reacts with H 2 at 50˚C to produce 3700 mol HCO 2 H mixture over RuH 2 [P(CH 3 ) 3 ] 4 mixed with NEt 3 [15][16]. Kolesnichenko N.V. [17] reported that the hydrogenation of carbon dioxides was performed over reformative Ruthenium at room temperature. Homogeneous hydrogenation of carbon dioxide could get high yield for purpose products such as formate esters, formamides, CO, methanol and other products, while it need high pressure(more than 10PMa) and batch operation, and some noble metal used in catalyst are difficult to recovery in the homogeneous system [18][19][20][21][22][23][24].…”

Functionalized catalyst preparation is a new and attractive method for hydrogenation of carbon dioxides. Three kind of carriers were functionalized firstly and then Ru was immobilized on the carriers. Continuous catalytic hydrogenation process was used to evaluate the activity of the catalyst on fixed-bed. It was found that the main production are formic acid and CO at 10MPa, and both the selectivity and recovery of CO are more than 90%, the hydrogen reaction mechanism could be explained with the reversed water gas reaction process. This may offer a new way for the reuse of CO2.

The (PNP)IrH 3 (2,6-bis(diisopropylphosphinomethyl)pyridine iridium trihydride) complex by Nozaki is a highly active and selective catalyst for CO 2 hydrogenation to formic acid in aqueous KOH. Previous theoretical investigations found that regeneration of the catalyst is the rate-determining step in this reaction. In the current article we present results from a computational study using density functional theory in order to consider the possibility of sequential insertion of two CO 2 molecules in two Ir−H bonds before the reaction with hydrogen. We found that insertion of a second CO 2 molecule is indeed possible; moreover, this sequential insertion allows formation of a more electrophilic iridium monohydride intermediate, and thereby the process of H 2 cleavage is facilitated. In addition, we considered the influence of ligands coplanar with the PNP ligand on the energy of CO 2 insertion into the (PNP)IrH 2 X complex and found that σand π-donating ligands promote the reaction.
