Abstract

The widespread application of mixed metal iron oxide materials in diverse environmental contexts makes them highly significant in heterogeneous catalysis. This study focuses on the synthesis of CeCa_xFe_1-xO_3-δ (x = 0, 0.2, 0.5, 0.8, and 1) nanomaterials using the sol–gel method and explores their structural, electrical, magnetic, optical, and photocatalytic properties. Comprehensive characterization was performed using Powder X-ray Diffraction (PXRD), Fourier Transform Infrared Spectroscopy (FTIR), High-Resolution Transmission Electron Microscopy (HRTEM), Brunauer–Emmett–Teller (BET) surface area analysis, Vibrating Sample Magnetometry (VSM), and UV–Visible Diffuse Reflectance Spectroscopy (UV-DRS). The diffraction peaks confirmed the formation of CeFeO₃-based structures. The magnetic behavior of the materials was analyzed through saturation magnetization, remanent magnetization, and coercivity. The optical properties, particularly in the visible region, motivated further exploration of the photo-Fenton activity of these nanomaterials, highlighting their potential in environmental remediation applications.

合金CeCaxFe1-xO3-δ：一种用于光fenton降解的掺钙氧化铈铁纳米材料

混合金属氧化铁材料在各种环境条件下的广泛应用，使其在多相催化方面具有重要意义。本研究采用溶胶-凝胶法制备了CeCaxFe1-xO3-δ (x = 0,0.2, 0.5, 0.8, 1)纳米材料，并对其结构、电学、磁学、光学和光催化性能进行了研究。采用粉末x射线衍射（PXRD）、傅里叶变换红外光谱（FTIR）、高分辨率透射电子显微镜（HRTEM）、布鲁诺尔-埃米特-泰勒（BET）表面积分析、振动样品磁强计（VSM）和紫外-可见漫反射光谱（UV-DRS）对样品进行了综合表征。衍射峰证实了cefeo3基结构的形成。通过饱和磁化、剩余磁化和矫顽力分析了材料的磁性行为。这些纳米材料的光学性质，特别是在可见光区域的光学性质，促使人们进一步探索它们的光芬顿活性，突出了它们在环境修复中的应用潜力。

期刊介绍： The journal offers a common reference and publication source for workers engaged in research on the experimental and theoretical aspects of crystal growth and its applications, e.g. in devices. Experimental and theoretical contributions are published in the following fields: theory of nucleation and growth, molecular kinetics and transport phenomena, crystallization in viscous media such as polymers and glasses; crystal growth of metals, minerals, semiconductors, superconductors, magnetics, inorganic, organic and biological substances in bulk or as thin films; molecular beam epitaxy, chemical vapor deposition, growth of III-V and II-VI and other semiconductors; characterization of single crystals by physical and chemical methods; apparatus, instrumentation and techniques for crystal growth, and purification methods; multilayer heterostructures and their characterisation with an emphasis on crystal growth and epitaxial aspects of electronic materials. A special feature of the journal is the periodic inclusion of proceedings of symposia and conferences on relevant aspects of crystal growth.
