Fouling is a significant issue in wastewater treatment processes, leading to reduced efficiency and increased operational costs. Perovskite materials have emerged as a promising solution for antifouling treatment in wastewater systems due to their unique properties and versatile applications. This book chapter provides an overview of the recent advancements in perovskite-based antifouling strategies and highlights the challenges that need to be addressed for their practical implementation. Traditional antifouling strategies often involve the use of toxic chemicals that have detrimental effects on marine ecosystems. Therefore, there is a growing need for environmentally friendly and sustainable alternatives. In recent years, perovskite materials have emerged as a promising candidate for antifouling treatments due to their unique physicochemical properties. The use of perovskite materials in antifouling applications primarily relies on two approaches: photodynamic and photocatalytic mechanisms. Photodynamic antifouling involves the generation of reactive oxygen species (ROS) upon exposure to light, which can effectively disrupt and prevent the attachment and growth of fouling organisms. On the other hand, photocatalytic antifouling employs perovskite materials as catalysts to trigger chemical reactions that degrade fouling organisms or their adhesion mechanisms. By harnessing their unique properties, perovskite-based coatings have demonstrated significant antifouling capabilities. Continued research and development efforts are necessary to overcome technical challenges and evaluate the long-term effectiveness and environmental implications, ultimately paving the way for the practical application of perovskite-based antifouling treatments in diverse marine industries.
