Special Issue Information

Dear Colleagues,

Photocatalytic wastewater treatment emerges as an efficient, environmentally friendly, and adaptable solution to various water sources, making it a promising option for cleaning wastewater, yet is limited in terms of its affordable scalability. This Special Issue aims to cover a comprehensive range of topics within the domain of photocatalysis in treating wastewater. We believe that your expertise in this field would greatly enrich our Special Issue and contribute to the advancement of knowledge in this critical area. We encourage submissions that address, but are not limited to, the following themes:

  • Photocatalytic reactor designs and optimization;
  • Catalyst materials and their development;
  • Operational strategies and scale-up considerations;
  • Novel approaches and emerging technologies;
  • Assessment of environmental impact and sustainability;
  • Economic feasibility and cost effectiveness.

Your research on this topic has been particularly impactful, and we would be delighted if you could contribute a manuscript on this subject. Your unique insights and expertise would be invaluable in furthering the discussion on this important topic. The journal Water is a prestigious publication known for its commitment to rigorous peer review and high-quality research. Your participation in this Special Issue would not only enhance your academic profile but also contribute to the advancement of knowledge in the field. The deadline for manuscript submissions is August 2024. Please let us know if you would be interested in contributing, and we can provide further details on manuscript preparation and submission guidelines. We look forward to the possibility of working with you on this exciting project.

Photocatalytic degradation technology has received much attention from researchers in the last few decades, due to its easy and cost-effective nature. A lot of review articles have been published on dyes via photocatalytic degradation, but most of the review articles lack a detailed and in-depth photocatalytic degradation mechanism of dyes. Numerous review articles are available on photocatalysis. Here, in this review article, we are mainly focused on the complete and in-depth photocatalytic degradation mechanism of four commonly used dyes such as Malachite Green, Methylene Blue, Congo Red and Rhodamine B, which will be highly useful for the new researchers that work on dyes’ photocatalytic degradation. Initially, various aspects of dyes have been included in this review article, comprehensively. The main focus was on the covalent organic framework-based photocatalysts for dyes’ photocatalytic degradation, due to their porous nature and various unique properties. Various synthesis routes and the photocatalytic performance of covalent organic frameworks and composite of covalent organic frameworks have been highlighted in this review article. In the last section of this review article, the main stimulus was the four mentioned dyes’ properties, uses, and toxicity, and the photocatalytic degradation mechanism through various paths into environmentally friendly and less-harmful compounds in the presence of photocatalysts. Factors effecting the photocatalytic degradation, economic cost, challenges and future aspects of photocatalytic technology were also included in this review article. This review article will be highly useful for those researchers that work on the photocatalytic degradation of various dyes and search for the complete degradation of complex dye molecules.
