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.

八面体核壳双金属催化剂M @ UIO-67（M = Pt-Pd纳米颗粒，Pt-Pd纳米笼）：增强CO2转化的金属纳米笼

基于分支的Pt-Pd纳米颗粒（Pt-Pd _NPs）或Pt-Pd纳米笼（Pt-Pd _NCs）组装基于Zr的金属有机骨架催化剂M @ UIO-67（M = Pt-Pd纳米颗粒，Pt-Pd纳米笼））作为UIO-67的核，并控制条件以制造一对一的核-壳复合材料：在一个UIO-67纳米八面体中一个Pt-Pd纳米颗粒。与Pt-Pd _NPs @ UIO-67相比，Pt-Pd _NCs @ UIO-67的逆水煤气变换反应具有更高的CO ₂转化率（26.88％），其优异的性能归因于其中空结构。 Pt–Pd纳米笼。
