Environmental pollution caused by persistent organic contaminants poses a significant threat to ecosystems and public health. Conventional treatment methods often fall short in effectively eliminating these pollutants, particularly at low concentrations. In recent years, photocatalytic biotechnology has emerged as a powerful and sustainable strategy for environmental cleanup, offering the potential for complete mineralization of toxic substances under light irradiation. This presentation will explore the latest advancements in photocatalytic materials, with a focus on nanostructured semiconductors, heterojunctions, and biomaterial-integrated catalysts that enhance photocatalytic efficiency. Emphasis will be placed on the design and modification of photocatalysts to optimize light absorption, charge separation, and surface reactivity. Furthermore, the integration of biotechnological approaches, such as enzyme-assisted degradation and microbial synergies, will be discussed to demonstrate how biological and photocatalytic systems can work in tandem for improved pollutant removal. Mechanistic insights into reactive oxygen species (ROS) generation, electron-hole dynamics, and pollutant interaction pathways will be highlighted, providing a comprehensive understanding of how these materials function at the molecular level. Case studies involving the degradation of industrial dyes, pharmaceuticals, and endocrine-disrupting chemicals will illustrate practical applications and scalability prospects. By bridging materials science, photocatalysis, and biotechnology, this talk aims to present a holistic approach to environmental remediation, offering innovative pathways toward cleaner and more resilient ecosystems.
