Abstract

Wastewater remediation is a prominent concern that should be addressed, as it is a critical problem that damages natural resources and has a negative impact on living organisms. In this study, the synthesis of copper ferrite and silver doped-copper ferrite nanoparticles named CuFe2O4 and AgXCuFe2O4 using Monsonia burkeana (M. burkeana) as a fuel and their photocatalytic performance against the textile pollutant, Methylene blue (MB) and the pharmaceutical pollutant, sulfisoxazole (SSX) was reported. The physical, optical, spectroscopic, and surface analyses of the as-prepared nanoparticles were characterized using various techniques. XRD confirmed the crystalline structure of Ag-CuFe2O4 and the incorporation of silver on the surface of the nanoferrites. FTIR analysis indicated the formation of a single-phase spinel crystalline structure with two sub-lattices (Td and Oh). UV–Vis absorption spectra of silver-substituted copper ferrite revealed that the band gap energy (Eg) decreased with increasing crystallite size. Upon testing their degradation efficiency, at pH 12, the highest degradation of 99 % after 60 min for the 7 % AgCuFe2O4 was reported, and the rate of the reaction was found to be 0.09769 min−1. The 7 % Ag-CuFe2O4 catalyst could be reused more than 4 times with a minimal loss in photostability and the e and •O2- were the primary species responsible for MB degradation. The photocatalyst 7 %Ag-CuFe2O4, showed a 60 % decomposition for the antibiotic after 120 min of UV-radiation. The 7 % Ag-CuFe2O4 photocatalyst displayed superior magnetic recovery capability under the action of the external magnetic field. These developments in this study offer wide promising applications in water environmental remediation.

用于染料和抗生素光降解的铜铁氧体沉积银纳米粒子的绿色合成
废水修复是一个亟待解决的突出问题,因为它是一个破坏自然资源并对生物产生负面影响的关键问题。本研究以Monsonia burkeana(M. burkeana)为燃料,合成了名为CuFe2O4和AgXCuFe2O4的铜铁氧体和银掺杂铜铁氧体纳米粒子,并报道了它们对纺织污染物亚甲基蓝(MB)和医药污染物磺胺异噁唑(SSX)的光催化性能。利用各种技术对制备的纳米颗粒进行了物理、光学、光谱和表面分析。XRD 证实了 Ag-CuFe2O4 的晶体结构以及银在纳米铁氧体表面的结合。傅立叶变换红外光谱分析表明形成了具有两个子晶格(Td 和 Oh)的单相尖晶石晶体结构。银取代铜铁氧体的紫外可见吸收光谱显示,带隙能(Eg)随晶体尺寸的增加而降低。在测试它们的降解效率时,在 pH 值为 12 的条件下,7% 的 AgCuFe2O4 在 60 分钟后的降解率最高,达到 99%,反应速率为 0.09769 min-1。7 %Ag-CuFe2O4 催化剂可重复使用 4 次以上,光稳定性损失极小,而 e- 和 -O2- 是造成甲基溴降解的主要物种。光催化剂 7%Ag-CuFe2O4 在紫外线照射 120 分钟后,抗生素的分解率为 60%。在外部磁场的作用下,7 %Ag-CuFe2O4 光催化剂显示出卓越的磁性恢复能力。这项研究的这些进展为水环境修复提供了广阔的应用前景。
