Direct hydrogenation of CO2 on deposited iron-containing catalysts under supercritical conditions

The hydrogenation of CO₂ in the supercritical state on supported Fe/TiO₂ catalysts (0.5–1% iron) at 350–550 °C affords carbon monoxide and methane, the conversion of CO₂ approaching 24%. The work demonstrates the possibility of significant increase in the productivity of CO₂ hydrogenation process and prolongation of the working time of the catalyst.
