Advances in Photocatalytic Water and Wastewater Treatment Processes

Dear Colleagues,

The urgency for sustainable and efficient water as well as wastewater treatment methodologies is pressing in the face of global challenges such as increasing pollution, the scarcity of clean water, and stringent environmental regulations. Photocatalytic water treatment processes represent a promising avenue for addressing these challenges due to their ability to decompose organic pollutants and inactivate microbial contaminants under light irradiation. These processes, which make use of recent advancements in materials science and catalysis, offer a green and energy-efficient alternative to conventional treatment methods. However, the field is still evolving, with significant opportunities for innovation in terms of catalyst design, reaction mechanisms, equipment design, system integration, and scalability. Understanding the complexities and optimizing the efficiencies of these processes are crucial for their practical application and the broader goal of sustainable water management.

This Special Issue on “Advances in Photocatalytic Water and Wastewater Treatment Processes” seeks high-quality works focusing on the latest developments in the field. We invite contributions that explore multidisciplinary, innovative photocatalytic materials, mechanisms, and methodologies that enhance the efficiency and applicability of water as well as wastewater treatment. Topics include, but are not limited to, the following:

• Development and characterization of novel photocatalysts for water and wastewater treatment;
• Mechanistic insights into the photocatalytic degradation of pollutants;
• Design and optimization of photocatalytic reactors as well as reaction systems;
• Integration of photocatalytic processes with other water treatment technologies;
• Pilot-scale studies on and scalability of photocatalytic water treatment processes;
• Life cycle assessments, economic analyses, and sustainability studies of photocatalytic treatment systems;
• Photocatalytic removal of emerging contaminants from water and wastewater.

We encourage contributions that provide new insights, represent significant advances, and contribute to the knowledge and application of photocatalytic water treatment processes. The findings should have implications for the design, operation, and optimization of treatment systems, aiming at the enhancement of water quality and environmental sustainability.
