今天给大家分享的是2015年5月份 《rsc advances》上发表的一篇名为：preparation and catalytic properties of pd nanoparticles supported on micro-crystal dut-67 mofs

文章摘要如下：

zr-based mofs usually feature exceptionally high thermal and chemical stability, which suggests that composites of noble metals and zr-based mofs could have wide industrial applications. in this work, we report the synthesis and characterization of pd nanoparticles (of three different loadings: 0.3%, 0.5% and 1.0%) supported on micro-crystal dut-67 mofs. via sem, tem and xps characterization methods, it was found that the pd nanoparticles were well dispersed on the interface of the mof micro-crystals, with a diameter of 3.5 nm, and both the dangling organic groups and the cavities of the mofs play important roles. furthermore, pxrd, ir, tga and n₂adsorption measurements confirmed that the composites are very robust. studies on the catalytic properties indicated that they have good catalytic performance with a conversion of 99% and selectivity of 89% in the suzuki coupling reaction. by a series of explorations, we found the best catalytic conditions are an ethanol–water mixed solvent as the medium, k₂co₃ as the base and a temperature of 70 °c. moreover, good catalytic properties were also shown for the hydrogenation of nitrobenzene, where the optimum temperature was 60 °c, and a conversion of 99% and selectivity of 99% were achieved.
