In this study, spherical sandwich Au@Pd@UIO-67/Pt@UIO-n (n = 66, 67, 69) core-shell catalysts were assembled. Au nanoparticles (NPs) were used as the core for the epitaxial growth of Pd shells, and Au@Pd core-shell NPs were successfully encapsulated in the center of monodispersed Au@Pd@UIO-67 nanospheres. Pt NPs were fully fixed onto the nanosphere surfaces to obtain Au@Pd@UIO-67/Pt composites; further coating with UIO-n led to Au@Pd@UIO-67/Pt@UIO-n, in which Pt NPs are sandwiches between the Au@Pd@UIO-67 core and a 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 CO2 conversion, and the UIO-n component effectively regulated the reverse water-gas shift (RWGS) reaction.

Nanometer range spherical cores of particular semiconductor compounds surrounded by an ultrathin metal shell that is commonly made of gold or silver. This configuration gives the nanoshells highly tunable optical properties. They have potential in biomedicine for diagnosis and therapy.
Nanoparticles produced from metals whose uses include biosensors, optics, and catalysts. In biomedical applications the particles frequently involve the noble metals, especially gold and silver.
Supramolecular networks that consist of ordered arrangements of organic electron donor linkers (usually ditopic or polytopic organic carboxylates) and metal cations. They can have an extremely high surface area and adjustable pore size that allows for the insertion of other molecules capable of various functions such as catalysis, capture of carbon dioxide, and drug delivery.
Organic polymeric materials which can be broken down by naturally occurring processes. This includes plastics created from bio-based or petrochemical-based materials.
