摘要

摘要 以壳聚糖为模板,硝酸铈(III)和硫酸铈(IV)为起始物质,氨水为沉淀剂,采用共沉淀法制备了纳米氧化铈(CeO2)颗粒。根据粉末 X 射线衍射数据,反应体系中形成了面心立方相的铈镧矿。相干散射区的大小不超过 ⁓3 nm。傅立叶变换红外光谱数据表明聚合物分子与无机成分发生了相互作用。与壳聚糖相比,含有 Ce(III) 和 Ce(IV) 的复合材料的 N-H 吸收带发生了移动,这表明氨基与聚合物中的 CeO2 颗粒发生了相互作用。使用壳聚糖作为合成 CeO2 纳米粒子的基质表明,这种方法更经济、更容易生产出用于各种应用的纳米材料。

In situ Synthesis of Nano-CeO2 Composite with Chitosan

Abstract

Nanosized cerium oxide (CeO2) particles were prepared by co-precipitation using chitosan as a template, cerium(III) nitrate and cerium(IV) sulfate as starting substances, and aqueous ammonia as a precipitating agent. According to powder X-ray diffraction data, cerianite with face-centered cubic phase is formed in the reaction systems. The size of the coherent scattering regions is not more than ⁓3 nm. Fourier transform IR spectroscopy data indicate to interaction of polymer molecules with the inorganic component. The shift of N–H absorption bands for composites containing Ce(III) and Ce(IV) compared to those of chitosan indicates that amino groups interact with CeO2 particles loaded in the polymer. The use of chitosan as a matrix for the synthesis of CeO2 nanoparticles showed that this approach is more economical and facile to produce nanomaterials for various applications.
