Аннотация: Noble metals nanoparticles exhibit outstanding catalytic ability in various reactions and it is of great significance to provide suitable supports for them. A ferrocene based metel-organic framework, named FMOF was synthesized using ZrCl4 and 1,10-ferrocene-dicarboxylic acid (FDC) through a tradition sol- vothermal method. The as-prepared FMOF featured nanosheet morphology with a thickness of ca.10 nm and lateral size of ca. 500 nm. Since the Fe2þ in the FDC ligands could act as a reducing agent, this FMOF was employed for the in-situ reduction of Pd2þ and the Pd nanoparticles (NPs) with a diameter of ca. 3.5 nm were successfully obtained and loaded on the surface of FMOF. Though this facile approach Pd/ FMOF with Pd loading amount of 3.39 wt% was obtained and no obvious change of the crystal structure was found after the reduction process for FMOF. It was found that the Pd/FMOF performed good catalytic activity in the oxidation of benzyl alcohol with conversion of 89.3%, and the catalytic activity maintained well after 3 cycles.
