This paper aims to fabricate of (PEO-PVP) blend doped with SnO2/MnO2 NPs for photodegradation of organic pollutants with low cost, high activity high propagation and anti-aggregation of nanoparticles compare with other materials.The polymer blend was prepared with ratio: 80 wt.% PEO and 20 wt.% PVP. The structural and optical properties of (PEO-PVP-SnO2-MnO2) nanocomposites have been studied in wavelength range (220–820) nm. The photodegradation behavior for (PEO-PVP-SnO2-MnO2) nanocomposites against organic pollutants has been investigated. The results indicated that the absorbance of (PEO–PVP) blend increases about 51% with adding of 4.5 MnO2NPs. The energy gap decreased for allowed and forbidden transitions about 55% and 91%, respectively, by adding of 4.5 MnO2NPs, this behavior is useful for optoelectronics, photocatalysis, the solar cells and diodes fields with low cost and light weight. Finally, the photodegradation activity of (PEO-PVP) blend and (PEO-PVP-SnO2) were increased with increasing of the MnO2 NPs ratios. The (PEO–PVP–SnO2–MnO2) NCs with 4.5 wt% of MnO2 NPs have photodegradation ratio 59%.

用于光降解有机污染物的 SnO2/MnO2 掺杂 PEO/PVP 混合物的增强结构和光学特性

本文旨在制备掺杂SnO 2 /MnO 2 NPs的(PEO-PVP)共混物,与其他材料相比,具有低成本、高活性、高传播和纳米颗粒抗聚集的光降解有机污染物的特性。比例:80 wt.% PEO 和 20 wt.% PVP。(PEO-PVP-SnO 2 -MnO 2 ) 纳米复合材料的结构和光学特性已在波长范围 (220–820) nm 内进行了研究。研究了(PEO-PVP-SnO 2 -MnO 2)纳米复合材料对有机污染物的光降解行为。结果表明(PEO-PVP)共混物的吸光度随着4.5 MnO 2 的加入增加了约51%NP。通过添加4.5 MnO 2 NPs,允许跃迁和禁止跃迁的能隙分别降低了约55%和91%,这种行为对于低成本和轻质的光电、光催化、太阳能电池和二极管领域很有用。最后,(PEO-PVP) 共混物和(PEO-PVP-SnO 2 )的光降解活性随着MnO 2 NPs 比例的增加而增加。含有 4.5 wt% MnO 2 NPs的 (PEO-PVP-SnO 2 -MnO 2 ) NCs 具有59% 的光降解率。
