Special Issue Information
Dear Colleagues,
Photocatalytic technology stands out as a straightforward, energy-efficient, safe, and eco-friendly approach for environmental purification. However, it grapples with challenges including low photon utilization, inadequate photoresponse, limited active sites, rapid electron-hole pair recombination, and a propensity for aggregation. To conquer these issues, researchers have engineered innovative photocatalysts, such as metal–organic frameworks, two-dimensional materials, and composite semiconductors, which boast enhanced light absorption efficiency and an expanded light response spectrum. Additionally, techniques like doping, constructing heterostructures, and surface modification can improve the separation efficiency of photogenerated electron-hole pairs, thereby reducing recombination rates and enhancing photocatalytic activity.
Photocatalysts are widely utilized for the degradation of pollutants in water, air, and soil. Among these, persistent organic pollutants, volatile organic compounds, and antibiotics in the environment are particularly of interest to researchers. Simultaneously, researchers are actively exploring the synergistic effects of photocatalytic technology with other technologies, such as electrocatalysis and biocatalysis, to achieve the more efficient degradation of pollutants. As research deepens, the application prospects of photocatalytic technology in the field of environmental remediation are expected to become even broader.
Therefore, this Special Issue aims to consolidate and disseminate knowledge in the field. We invite you to contribute your research article, communication, or review related to the photocatalytic degradation of pollutants.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Separations is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
