With the development of industry, serious pollution has emerged in water resources. This poses serious problems for the health of living things and the environment. To deliver a sustainable future, producing effective, low-cost, and reusable photocatalysts in wastewater treatment is important. In this study, FeO/MetCel@Pb photocatalysts were synthesized for the first time. The properties of FeO/MetCel@Pb photocatalysts were characterized by Fourier Transform Infrared Spectroscopy (FTIR), X-ray Diffraction (XRD), Brunauer-Emmett-Teller (BET), Ultraviolet-Visible Spectrophotometry (UV-Vis), Vibrating Sample Magnetometry (VSM), Electron Spin Resonance (ESR), Scanning Electron Microscopy (SEM), Transmission Electron Microscope (TEM), and X-ray Photoelectron Spectroscopy (XPS). The average particle size, surface area, band gap energy, saturation magnetization, resonance magnetic field, and g-factor values of the FeO/MetCel@Pb photocatalysts measured as 63.88 nm, 40.59 m g, 5.71 eV, 24.80 emu g, 390.15 mT, and 1.731, respectively. XPS analysis showed signals confirming strong CO bonds, FeO bonds, Fe, and Fe at binding energies of 286.04, 528.00, 711.39, and 723.84 eV, respectively. Also, FeO/MetCel@Pb photocatalysts were used for the first time in the dye degradation. The degradation of methylene blue (MB), methyl orange (MO), phenol red (PR), alizarin yellow (AY), and bromthymol blue (BTB) dyes under ultraviolet-visible light for 30 min was determined as 100 %, 96.76 %, 94.51 %, 80.81 %, and 71.93 %, respectively. In the reusability study, FeO/MetCel@Pb photocatalysts showed a reduction rate of 1.70 % compared to the first cycle even after the fourth cycle. The stability and repeated reusability of FeO/MetCel@Pb photocatalysts without deformation were realized. Application of FeO/MetCel@Pb photocatalysts in real dyed water samples (even in mixed matrix samples) showed over 90 % dye degradation efficiency. This confirms that the photocatalyst is an effective catalyst in dye degradation. FeO/MetCel@Pb photocatalysts, which are economical, easy to prepare, and stable, will be an effective option for the removal of industrial waste paints (cationic and anionic dye) from aqueous systems. In addition, using these photocatalysts will provide ease of process, as well as time and cost savings.
随着工业的发展，水资源中出现了严重污染。这给生物健康和环境带来了严重问题。为了实现可持续发展的未来，制备用于废水处理的高效、低成本且可重复使用的光催化剂至关重要。在本研究中，首次合成了FeO/MetCel@Pb光催化剂。通过傅里叶变换红外光谱（FTIR）、X射线衍射（XRD）、布鲁诺尔-埃米特-泰勒（BET）、紫外-可见分光光度法（UV-Vis）、振动样品磁强计（VSM）、电子自旋共振（ESR）、扫描电子显微镜（SEM）、透射电子显微镜（TEM）和X射线光电子能谱（XPS）对FeO/MetCel@Pb光催化剂的性能进行了表征。FeO/MetCel@Pb光催化剂的平均粒径、表面积、带隙能量、饱和磁化强度、共振磁场和g因子值分别测得为63.88nm、40.59m²/g、5.71eV、24.80emu/g、390.15mT和1.731。XPS分析显示，在结合能分别为286.04、528.00、711.39和723.84eV处有信号证实了强CO键、FeO键、Fe²⁺和Fe³⁺。此外，FeO/MetCel@Pb光催化剂首次用于染料降解。在紫外-可见光下30分钟内，亚甲基蓝（MB）、甲基橙（MO）、酚红（PR）、茜素黄（AY）和溴百里酚蓝（BTB）染料的降解率分别测定为100%、96.76%、94.51%、80.81%和71.93%。在可重复使用性研究中，即使在第四个循环后，FeO/MetCel@Pb光催化剂与第一个循环相比降解率降低了1.70%。实现了FeO/MetCel@Pb光催化剂的稳定性和反复可重复使用性且无变形。FeO/MetCel@Pb光催化剂在实际染色水样（甚至在混合基质样品）中的应用显示染料降解效率超过90%。这证实了该光催化剂在染料降解中是一种有效的催化剂。FeO/MetCel@Pb光催化剂经济、易于制备且稳定，将是从水体系中去除工业废涂料（阳离子和阴离子染料）的有效选择。此外，使用这些光催化剂将使过程简便，同时节省时间和成本。
