摘要

摘要通过沉淀法和共沉淀法，在纳米纤维素基质中嵌入钯、氧化铜(I)和磁铁矿纳米粒子，并从相应金属的盐溶液中原位和异位获得了纳米复合材料。利用傅立叶变换红外光谱、X 射线衍射、扫描电镜和电子显微镜对所得复合材料的特性进行的研究表明，封装的纳米颗粒对纳米纤维素的形态和结构影响不大。在硝基苯的氢化过程中测试了纳米复合材料的催化性能。

Synthesis, Structure, and Catalytic Properties of Nanocomposites Based on Palladium, Copper(I) Oxide, and Magnetite Nanoparticles Embedded in a Nanocellulose Matrix

Nanocomposite materials based on palladium, copper(I) oxide, and magnetite nanoparticles embedded in a nanocellulose matrix by precipitation and coprecipitation methods were obtained in situ and ex situ from solutions of the salts of the corresponding metals. Studies of the characteristics of the resulting composites using Fourier transform IR spectroscopy, X-ray diffraction, SEM, and TEM showed that the encapsulated nanoparticles have an insignificant effect on the morphology and structure of nanofibrillar cellulose. The catalytic properties of the nanocomposites were tested in the hydrogenation of nitrobenzene.
