摘要：
Zr-based metal-organic framework catalysts M@UIO-67 (M = Pt-Pd nanoparticles, Pt-Pd nanocages) were assembled using branched Pt-Pd nanoparticles (Pt-Pd NPs ) or Pt-Pd nanocages (Pt-Pd NCs ) as cores in UIO-67, and the conditions were controlled to fabricate one-to-one core-shell composites: one Pt-Pd nanoparticle in one UIO-67 nano-octahedron. Compared with Pt-Pd NPs@UIO-67, the catalyst Pt-Pd NCs @UIO-67 exhibited higher CO2 conversion (26.88%) for the reverse water-gas shift reaction, the superior performance can be attributed to the hollow structure of Pt-Pd nanocages.
