Abstract

The present work reports formulation of nanohybrids of CuFe2O4 using polypyrrole (PPy) in the weight ratios of 1%, 3% and 5%. The synthesized nanohybrids were characterized using FTIR, UV–Vis, XRD and SEM–EDS. The optical band gaps were calculated to be 2.31 eV, 2.11 eV and 1.74 eV for 1-PPy/CuFe2O4, 3-PPy/CuFe2O4, and 5-PPy/CuFe2O4, respectively. The photocatalytic degradation of urea and polyethene (PE) was carried out under visible light irradiation to study the effect of degradation of pollutants in presence of an organic–inorganic hybrid photocatalyst. The nanohybrids showed superior photocatalytic performance when compared with pure CuFe2O4. The maximum photocatalytic degradation was found to be 62% within 120 min using 5-Ppy/CuFe2O4 as photocatalyst and 40% degradation of PE films was achieved under microwave irradiation. The catalysts showed promising results for the highly efficient degradation of polymers.

铜铁氧体/聚吡咯纳米杂化物的光催化性能:可见光诱导的尿素降解和微波辅助的聚乙烯薄膜降解研究
本研究报告介绍了使用聚吡咯(PPy)以 1%、3% 和 5%的重量比配制 CuFe2O4 纳米杂化物的情况。傅立叶变换红外光谱(FTIR)、紫外可见光谱(UV-Vis)、X射线衍射(XRD)和扫描电子显微镜(SEM-EDS)对合成的纳米杂化物进行了表征。经计算,1-PPy/CuFe2O4、3-PPy/CuFe2O4 和 5-PPy/CuFe2O4 的光带隙分别为 2.31 eV、2.11 eV 和 1.74 eV。在可见光照射下,对尿素和聚乙烯(PE)进行了光催化降解,以研究有机-无机杂化光催化剂对污染物降解的影响。与纯 CuFe2O4 相比,纳米杂化物显示出更优越的光催化性能。使用 5-Ppy/CuFe2O4 作为光催化剂,120 分钟内的光催化降解率最高可达 62%;在微波辐照下,聚乙烯薄膜的降解率为 40%。这些催化剂显示出高效降解聚合物的良好效果。
