Visualizing Size-Dependent Dynamics of CeO<sub>2−δ</sub>{100}-Supported CoO<sub><i>x</i></sub> Nanoparticles Under CO<sub>2</sub> Hydrogenation Conditions

Visualizing Size-Dependent Dynamics of CeO<sub>2−δ</sub>{100}-Supported CoO<sub><i>x</i></sub> Nanoparticles Under CO<sub>2</sub> Hydrogenation Conditions

Carbon dioxide is a major greenhouse gas. In order to optimize processes focused on its chemical valorization, one needs detailed information about the effects of CO<sub>2</sub> and/or CO<sub>2</sub>/H<sub>2</sub> mixtures on the structure and morphology of metal/...
