Efficient nanocatalyst with incredible performance is highly demanding in a heterogeneous catalysis system. Herein, we report the facile fabrication of uniform and highly stable Cerium Oxide nanoparticles (CeO NPs), through chemical precipitation method using sodium hydroxide as reducing agent. The synthesized material is characterized through highly sophisticated techniques including UV-Visible, FT-IR, SEM, AFM, XRD, and Zeta Sizer- Potential to check the particle formation, surface morphology, topography, crystalline nature, size, and surface potential. The heterogeneous catalytic performance of CeO NPs has been accomplished for the reduction of 2-nitroaniline from the aqueous media. The CeO nanocatalyst displayed excellent reusability, while the reduction in several repetitive catalytic cycles against 2-nitroaniline under optimized conditions. The CeO nanocatalyst shows 99.12% efficiency within 60s reaction time under a greener source of microwave radiation.
高效纳米催化剂在多相催化体系中具有很高的要求。在此，我们通过使用氢氧化钠作为还原剂的化学沉淀法，报告了均匀且高度稳定的氧化铈纳米粒子（CeO NPs）的简便制备。通过包括紫外-可见、FT-IR、SEM、AFM、XRD 和 Zeta 电位在内的高度复杂技术对合成材料进行了表征，以检查颗粒形成、表面形态、形貌、晶体性质、尺寸和表面电势。CeO NPs 的多相催化性能已用于从水介质中还原 2-硝基苯胺。CeO 纳米催化剂表现出优异的可重复使用性，而在优化条件下，在几次重复催化循环中对 2-硝基苯胺的还原。在微波辐射的绿色来源下，CeO 纳米催化剂在 60s 反应时间内显示出 99.12%的效率。
