Special Issue Information
Dear Colleagues,
Photocatalytic advanced oxidation processes for treating water and wastewater have been the subject of extensive research and technological advancements over the past three decades for their potential of being a low-cost, environmentally friendly, and sustainable approach. The major challenges restraining the commercialization of this technology are the low photoconversion efficiency, the cost associated with the UV source, post-recovery of photocatalysts, and the photocatalytic efficiency towards the degradation of emerging, recalcitrant contaminants. Research efforts are being made to develop novel catalytic materials with broader light absorption to utilize the sunlight effectively. Development of the hybrid catalytic materials for the advanced hybrid oxidation of contaminants is also gaining much attention due to the enhancement in reaction kinetics. The integration of photocatalysis with other conventional or advanced processes can complement each other for catalyst recovery, improved treatment efficiency and economic viability.
This Special Issue focuses on recent progress and trends in the development of engineered-photocatalytic nanomaterials, advancements in their immobilization and supports, photocatalytic reactor configurations, process optimization, its application in the removal of persistent organic pollutants including degradation byproducts from water and wastewater (domestic and industrial) and the combination of photocatalysis with other treatment technologies. We invite manuscript submissions of original research studies or review articles encompassing the recent findings and advancements in photocatalytic advanced oxidation processes for this Special Issue in Water.
