Spherical Sandwich Au@Pd@UIO-67/Pt@UIO-n (n = 66, 67, 69) Core–Shell Catalysts: Zr-Based Metal–Organic Frameworks for Effectively Regulating the Reverse Water–Gas Shift Reaction

Abstract

core and the UIO-n shell. The Au@Pd core−shell NPs efficiently controlled the morphology and structure of UIO-67 and enhanced the CO selectivity of the catalyst. Pt NPs increased the CO 2 conversion, and the UIO-n component effectively regulated the reverse water−gas shift reaction.

Recent Developments in the Modelling of Heterogeneous Catalysts for CO2 Conversion to Chemicals

“…Noble metal catalysts, mainly Pt and Rh based supported catalysts, have high activity towards hydrogen dissociation, relatively moderate strength with the adsorption of reaction intermediates and the incompletely filled D‐orbital electrons make them easier for the adsorption of reactants with moderate strength, which is further benefiting to form the intermediate “active compound” in RWGS reaction . Besides mentioned catalysts other metal catalysts as active components or as supports are Pd, Ni, Co, Fe, Fe supported on CNTs and carbide (Mo 2 C) catalyst …”

Engineering heterogenous catalysts for chemical CO2 utilization: Lessons from thermal catalysis and advantages of yolk@shell structured nanoreactors

“…Meanwhile, the Au@Pd@UIO-67/Pt@UIO-67 catalyst demonstrated ca. 35% CO 2 conversion with 80% CO selectivity at 400 °C [350]. In this case, it appears that the selectivity was governed by the UiO shell and the extra incorporation of the Pt aided in boosting conversion.…”

Advanced photocatalysts based on metal nanoparticle/metal-organic framework composites

“…This strategy can be regarded as a step-by-step method for synthesis of MOF/MNP/MOF composite with well-defined sandwich structure [86][87][88][89][90][91][92]. Typically, the synthesis procedure relies on the overgrowth of an additional MOF shell onto the supported MNP/MOF composite that is pre-synthesized by the simple adsorption method described formerly.…”
