The increasing presence of emerging contaminants (ECs) such as pharmaceuticals, personal care products, and endocrine-disrupting chemicals in water bodies poses a significant threat to environmental and human health. Traditional wastewater treatment processes are often inadequate in removing these persistent pollutants. Advanced oxidation processes (AOPs), particularly photocatalysis, have emerged as a promising technology for the degradation of ECs due to their ability to generate highly reactive species that can break down complex organic molecules into harmless byproducts.

Recent advancements in nanomaterials and the development of novel photocatalysts have significantly enhanced the efficiency and selectivity of photocatalytic processes. Researchers are now focusing on engineering photocatalysts with optimal band gaps, high surface areas, and improved photostability to achieve superior degradation performance under visible light irradiation. Additionally, the integration of photocatalysis with other treatment methods and the exploration of sustainable, low-cost materials are gaining traction to make these processes more economically viable and environmentally friendly.

This special issue aims to bring together cutting-edge research on the synthesis, characterization, and application of photocatalysts for the degradation of emerging contaminants. We invite contributions that explore innovative approaches, mechanistic insights, and practical applications of photocatalytic processes to address the pressing challenges in environmental remediation.

We look forward to receiving your groundbreaking contributions that will drive the field of environmental catalysis towards a cleaner and more sustainable future.

We welcome contributions that address the following themes:

1)Synthesis and characterization of novel photocatalysts, including nanomaterials and composite materials.

2)Mechanistic studies on the degradation pathways and kinetics of ECs under photocatalytic conditions.

3)Integration of photocatalysis with other treatment methods, such as adsorption, membrane filtration, and biological processes.

4)Development of sustainable, low-cost photocatalytic materials and systems.

5)Case studies and practical applications of photocatalysis in real-world environmental remediation scenarios.

We encourage the submission of various types of manuscripts, including original research articles, review articles, short communications, and perspective pieces. Contributions that provide new insights, address existing challenges, or propose innovative solutions in the field of environmental catalysis are particularly welcome. We aim to compile a comprehensive and multidisciplinary collection of works that will advance the understanding and application of photocatalytic processes for cleaner and more sustainable water resources.
