Boron nitride (BN) supported palladium (Pd) nanostructured catalyst, as an alternative support for heterogeneous reduction of nitrobenzene derivatives, was prepared by a mild reduction of a Pd precursor in water. The structural characteristics and distribution of the synthesized Pd nanoparticles (NPs) on BN support were investigated by transmission electron microscopy, scanning transmission electron microscopy, energy-dispersive x-ray spectroscopy and x-ray photoelectron spectroscopy methods. The potential and efficiency of the BN supported Pd NPs as an active and stable nanostructured catalyst were verified in the reduction of nitroaromatics. Excellent yields of the corresponding aryl amines in water were obtained and due discussion were included about the catalytic activity of the synthesized catalyst. It was also indicated that the nanostructured catalyst can be recycled at least for six consecutive cycles in the reduction of nitrobenzene, without losing significant activity....

氮化硼-钯纳米结构催化剂：有效还原水中的硝基苯衍生物

氮化硼（BN）负载的钯（Pd）纳米结构催化剂，可通过在水中轻度还原Pd前驱物来制备硝基苯衍生物异质还原的替代载体。通过透射电子显微镜，扫描透射电子显微镜，能量色散X射线能谱和X射线光电子能谱方法研究了BN载体上合成的Pd纳米颗粒的结构特征和分布。BN负载的Pd NPs作为活性和稳定的纳米结构催化剂的潜力和效率在硝基芳烃的还原中得到了证实。获得了相应的芳基胺在水中的优异产率，并且对合成催化剂的催化活性进行了适当的讨论。
