Abstract:
Thermo-catalytic hydrogenation of CO2 to fuels and chemicals is an effective way to utilize CO2, but it faces significant challenges due to low CO2 conversion and product selectivity. Here, we report a lattice-strained FeZnNa catalyst synthesized via a mechanochemical method (FeZnNa-G), showing a high selectivity for C4+ long-chain olefins (C4+ =) of 64.9% and C2+ = of 77.5% at a high CO2 conversion rate of 47.7%. We found that the lattice-contracted FeZnNa-G catalyst forms Na-enriched ZnO nano-islands on the surface after activation and a Na-ZnO/Fe5C2 structure with the presence of 97% Fe5C2, facilitating the formation of an HCOO* intermediate and enhancing CO2 activation. A high C4+ = space-time yield (STY) of 474.9 mg g cat -1·h-1 and an extremely low CO selectivity of ∼9.1% exhibited dual-high performance, significantly surpassing that in previous reports. This use of a lattice-strained catalyst offers a new strategy for the efficient conversion of CO2 into high-value olefins, and paves the way for potential industrial applications.

Reduction of Alkenes: Catalytic Hydrogenation
Metals like palladium, platinum, and nickel are commonly used in their solid forms — fine powder on an inert surface. As these catalysts remain insoluble in the reaction mixture, they are referred to as heterogeneous catalysts.

Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...
