The present study is based on a synthesis of facile, cheaper, well homogenized and highly stable Cerium Oxide nanostructures via chemical precipitation method. The synthesized nanoceria was subjected under different characterization tools. The UV–visible and FTIR study profile initially confirm the formation and existing functionalities in nanoceria. The XRD, SEM techniques were exploited the crystalline and untwined combined form rhombohedron shaped CeO₂ nanoparticles respectively. While zeta sizer measurements explained well arranged, mono-dispersity, size and charge over the surface of nanoceria, which was calculated to be 17 nm with a desirable charge of + 6.37 mV. Finally, the well-prepared nanoceria nanoparticles were successfully applied as effective heterogeneous catalyst for 4-nitrophenol reduction. Under optimized conditions the nanoceria exhibited enhanced activity for 99% reduction of 4-NP within 60 s reaction time under greener microwave irradiation.

本研究基于通过化学沉淀法合成的廉价，便宜，均质化和高度稳定的氧化铈纳米结构。合成的纳米氧化铈在不同的表征工具下进行处理。紫外可见和FTIR研究概况初步证实了纳米氧化铈的形成和现有功能。利用XRD，SEM技术研究了晶体和非缠绕结合形式的菱面体形CeO _2。纳米粒子。尽管zeta粒度仪的测量结果解释得井井有条，但纳米二氧化铈表面的单分散性，大小和电荷被计算为17 nm，理想电荷为+ 6.37 mV。最后，制备良好的纳米二氧化铈纳米颗粒已成功用作4-硝基苯酚还原的有效多相催化剂。在最优化的条件下，纳米氧化铈在更绿色的微波辐射下，在60 s反应时间内对4-NP降低99％的活性增强。
