Exploring the CeO<sub>2</sub> Support Morphology for the Carbon Dioxide Hydrogenation Reaction using Nickel Catalysts
The catalytic activity and stability are examined for the hydrogenation of carbon dioxide under atmospheric pressure over 2 wt % Ni/CeO2 nanorods (2Ni-CeNRs), nanocubes (2Ni-CeNCs), and nanopolyhedra (2Ni-CeNPs). The 2Ni-CeNR catalysts display excellent catalytic activity and higher stability compared with 2Ni-CeNC and 2Ni-CeNP catalysts. A comprehensive understanding of the surface atomic and electronic structure versus activity has been derived using high-resolution electron microscopy and spectroscopy techniques. High metal dispersion, strong metal–support interaction (SMSI) effect and abundant oxygen vacancies are deduced to play a crucial role in determining the catalytic activity and selectivity of the CO2 hydrogenation reaction.
