Metal-organic framework (MOF)-driven synthesis is considered as a promising alternative for the development of new catalytic materials with well-designed active sites. This synthetic approach is used here to gradually transform a new bimetallic MOF, with Pd and Fe as the metal components, by the in situ generation of aniline under mild conditions. This methodology results in a compositionally homogeneous nanocomposite formed by Fe-doped Pd nanoparticles that, in turn, are supported on iron oxide-doped carbon. The nanocomposite has been fully characterized by several techniques such as IR and Raman spectroscopy, TEM, XPS, and XAS. The performance of this nanocomposite as an heterogeneous catalyst for hydrogenation of nitroarenes and nitrobenzene coupling with benzaldehyde has been evaluated, proving it to be an efficient and reusable catalyst.
金属有机框架（MOF）驱动的合成被认为是开发具有精心设计活性位点的新型催化材料的一种有前途的替代方法。本文采用这种合成方法，在温和条件下通过原位生成苯胺逐步转化一种以钯和铁为金属组分的新型双金属MOF。该方法产生了一种由铁掺杂的钯纳米颗粒组成的成分均匀的纳米复合材料，这些纳米颗粒又负载在氧化铁掺杂的碳上。通过红外光谱、拉曼光谱、透射电子显微镜、X射线光电子能谱和X射线吸收光谱等多种技术对该纳米复合材料进行了全面表征。评估了该纳米复合材料作为非均相催化剂用于硝基芳烃氢化以及硝基苯与苯甲醛偶联反应的性能，证明它是一种高效且可重复使用的催化剂。
