Abstract

Abstract : By using H2 PdCl4 as a novel structure-directing agent, the shape of ZIF-8 is transformed from rhombic dodecahedron to cube. After H2 treatment, the as-obtained Pd/ZIF-8 nanocubes show efficient catalytic activity for nitrobenzene hydrogenation. Abstract : A palladium precursor (H2 PdCl4 ) has been utilized as a novel structure-directing agent for controlling the morphology of ZIF-8. Using reverse micelles as nanoreactors, the Pd/ZIF-8 nanocomposite with a uniform size distribution is obtained. It is revealed that Pd(ii ) can selectively coordinate with the (100) plane of ZIF-8. As a result, the morphology of ZIF-8 is transformed from rhombic dodecahedral to cubic. After hydrogen treatment, the as-obtained Pd NPs/ZIF-8 nanocubes show efficient catalytic activity for nitrobenzene hydrogenation, which is higher than that of the commercially available Pd/C catalyst.
