我们报道了一种Pd@CN催化剂，该催化剂由钯纳米颗粒负载在来自ZIF-67的n掺杂碳上。具有微孔/介孔结构的CN材料在负载Pd纳米粒子和提高催化性能方面得到了很好的发展。随着ZIF-67煅烧温度的升高，CN材料的BET表面呈现先升高后降低的趋势。此外，煅烧温度越高，CN材料中氮含量越低，苯酚加氢成环己酮的选择性越低。我们的Pd@CN600催化剂达到了约95%的转化率和约95%的选择性，并且在回收实验中表现出优异的稳定性。(C) 2016韩国工业与工程化学学会。Elsevier B.V.版权所有。
We reported a Pd@CN catalyst made of Pd nanoparticles supported on a N-doped carbon derived from ZIF-67. The CN materials with micro/mesoporous structures were well developed for the loading of Pd nanoparticles and improving the catalytic performances. With the increase of calcination temperature of ZIF-67, the BET surface of CN materials initially increased and then reduced. Moreover, the higher calcination temperature would lead to lower nitrogen content in CN materials, causing lower selectivity of phenol hydrogenation to cyclohexanone. Our Pd@CN600 catalyst achieved a conversion of ca. 95% and a selectivity of ca. 95%, and exhibited excellent stability during recycling experiments.
