In this study, nanoparticles of Fe₂O₃/Mn₂O₃ mixture were obtained using the sol–gel method. The synthesis uses the combination of polyvinyl alcohol (PVA) and tartaric acid (TA). Synthesized catalysts prove superior compared to those afforded from previous reports. To be specific, desired catalysts can be received at lower calcination temperature. Furthermore, their structures display higher uniformity in term of particle sizes. Finally, they show better performance for the photocatalytic degradation of model‐persistent organic compounds.

Fe2O3 / Mn2O3纳米粒子：制备及其在水中苯酚和对硫磷的光催化降解中的应用

在这项研究中，使用溶胶-凝胶法获得了Fe ₂ O ₃ / Mn ₂ O ₃混合物的纳米颗粒。合成使用聚乙烯醇（PVA）和酒石酸（TA）的组合。事实证明，与以前的报道相比，合成的催化剂更具优势。具体而言，可以在较低的煅烧温度下接收所需的催化剂。此外，它们的结构在粒度方面显示出更高的均匀性。最后，它们在模型持久性有机化合物的光催化降解方面显示出更好的性能。
