CO<sub>2</sub> Hydrogenation over Ni–Co/Ce<sub>0.6</sub>Zr<sub>0.4</sub>O<sub>2</sub> Catalysts for Light Hydrocarbons under Mild Conditions
Ni and Ni–Co metal nanoparticles supported on a Ce0.6Zr0.4O2 support (denoted as Ni/CZ-C and NiCo/CZ-C) were tested for the hydrogenation of carbon dioxide under mild conditions. The NiCo/CZ-C catalyst demonstrated remarkable performance, significantly decreasing the reaction temperature (200 °C) and achieving high selectivity toward short-chain hydrocarbons, specifically ethane and butane. In situ studies using diffuse reflectance infrared Fourier transform spectroscopy allowed for the monitoring of the evolution of methane formation and the proposal of a reaction scheme. Both catalysts produce carbonate species, which are further hydrogenated to produce CH4. Notably, with the NiCo/CZ-C catalyst, additional hydrocarbons, such as ethane and butane, were also detected.
