Efficient Photothermal CO Hydrogenation into C₂₊ Hydrocarbons on in situ Generated Fe⁰ in Fe₅C₂ Active Sites via Cu-Promoted Hydrogen Dissociation and Spillover

Photothermal hydrogenation of carbon monoxide (CO) holds the potential to generate valuable C2+ chemicals using renewable solar energy. However, its activity and selectivity towards C2—C3 alkanes are limited compared to conventional thermal catalysis. In this study, a robust catalyst consisting of Cu/Fe₃O₄ nanoparticles on Mo₂CTx MXene was developed, showing enhanced photothermal C2—C3 production. The Cu component plays a crucial role in H₂ dissociation and subsequent H spillover, facilitating the in situ generation of Fe⁰ in Fe₅C₂ active sites and thus efficiently promoting photothermal CO hydrogenation. As a result, a 78.5% CO conversion and 51.3% C2+ selectivity were achieved at a high gas hourly space velocity (GHSV) of 12000 mL·gcat⁻¹·h⁻¹ and 2.5 MPa in a flow reactor at 320 °C. The overall C2—C3 yield reached 23.6% with the Cu/Fe₃O₄/Mo₂CTx catalysts, marking a 2.8-fold increase compared to the performance of the bare Fe₃O₄/Mo₂CTx catalyst.
