Abstract: The present disclosure relates to oxygen-defect-engineered dysprosium orthoferrite (DyFeO3) nanomaterials, supported nanocomposites, methods of preparation, and reusable photocatalytic systems for wastewater treatment. The disclosed approach comprises preparing DyFeO3 nanomaterials, modifying their oxygen-defect characteristics through a controlled post-treatment process, and immobilizing the resulting material on or within a suitable porous support. The supported nanocomposite is configured for contact with wastewater during irradiation under conditions suitable for photocatalytic treatment of organic contaminants. A recovery and regeneration procedure may be employed to facilitate repeated use of the supported catalyst. The proposed system is intended to integrate controlled material characteristics, photocatalytic treatment, catalyst retention, and reuse. Structural characterization, photocatalytic testing, comparative evaluation, and leaching studies are used to assess material properties, treatment performance, and stability. The invention provides a framework for developing recoverable DyFeO3-based photocatalytic materials and wastewater-treatment systems, subject to experimental validation and assessment of applicable prior art.
