The objective of this study is to enhance the photocatalytic capabilities of kaolin clay to improve its efficiency in environmental remediation. Various techniques were employed to modify kaolin clay, including heat treatment, acid modification, and material integration. These methods aimed to reduce its bandgap and improve its selective adsorption properties, thereby enabling better visible light activation and pollutant removal. The study discovered that modified kaolin-derived nanomaterials exhibit remarkable potential in breaking down pollutants, disinfecting, capturing heavy metals, and eliminating airborne contaminants. These advanced materials have been successfully used in water filtration, air purification, and the development of self-cleaning surfaces. The modifications increased surface area, adsorption capacity, and overall catalytic performance. Unmodified kaolin, with its broad bandgap, has limitations that hinder its ability to be driven by visible light for photocatalytic purposes and to selectively absorb specific pollutants, including heavy metals. The novelty of this research lies in the systematic exploration and optimization of diverse modification strategies for kaolin clay, showcasing its versatility in photocatalytic applications. The tailored modifications of kaolin to address specific environmental needs have the potential to be a cost-effective and eco-friendly solution for sustainable environmental restoration.
