Abstract

In this study, the Zr-based metal-organic framework (MOF) catalysts Pd@UiO-66, Pd@Pt_NPs@UiO-66, and Pd@Pt_NCs@UiO-66, were assembled. Core-shell Pd@Pt nanoparticles (NPs), in which cubic Pd NPs serve as the core for the epitaxial growth of Pt shells, were encapsulated into UiO-66 to obtain Pd@Pt_NPs@UiO-66, which were subjected to further etching to obtain Pd@Pt nanocages (NCs) in UiO-66. CO₂ conversion and CO selectivity in reverse water-gas shift reaction with Pd@Pt_NCs@UiO-66, Pd@Pt_NPs@UiO-66, and Pd@UiO-66 were 19.6% and 72.3%, 16.2% and 85.9%, and 15.6% and 52.3%, respectively. This proves that the cubic Pd@Pt_NCs can enhance the CO₂ hydrogenation and long-term stability.
