Fabrication of Pd@ZIF-8 catalysts with different Pd spatial distributions and their catalytic properties

Ultra‐small and highly dispersed Pd nanoparticles inside the pores of ZIF‐8: Sustainable approach to waste‐minimized Mizoroki–Heck cross‐coupling reaction based on reusable heterogeneous catalyst

“…Because of the electrostatic interaction of negatively charged NHC, functionalized Pd exhibits an excellent environment for stabilizing Pd NPs, and consequently prevents their undesired agglomeration. The obtained Pd NPs show the smallest sizes among metallic nanoparticles stabilized by solid support materials, especially the common MOFs reported to date . On the basis of transmission electron microscopy (TEM) analysis, ultra‐small Pd NPs were well dispersed into the cavities of ZIF‐8.…”

Continuous and complete conversion of high concentration p‐nitrophenol in a flow‐through membrane reactor

“…powdered catalysts easily aggregate or leak, and it is difficult to separate them from the reaction system. 20 Catalytic membranes exhibit good particle distribution, and no additional separation is required. 21,22 Moreover, the porous membrane structure and flow-through mode can enhance the catalytic efficiency by increasing mass transfer.…”

Synthesis of Pd/SBA-15 catalyst employing surface-bonded vinyl as a reductant and its application in the hydrogenation of nitroarenes

“…For example, PVP is usually used as a protective agent to stabilize the palladium nanoparticles. 24 An interesting method for the preparation of supported palladium nanoparticles is to employ a reducing agent uniformly bound to the surface of the supports. The palladium salt then could only be reduced on the surface of the supports and the resulting palladium nanoparticles will not enlarge as there are no more reducing agents nearby.…”
