Special Issue Information
Dear Colleagues,
Having clean air in the environment has become a high-priority objective within environmental policy and sustainable development strategies. The World Health Organization recently established (September 2021) the new guideline limits for atmospheric pollutants, meaning that 99% of world population breathe in polluted air. In order to deal with this problem, photocatalysis has emerged as a technology with the ability to remove pollutant gases, such as NOx, CO2, or VOCs. This technology is at the forefront (more than 16,000 search results in 2022 only; Google Scholar) due to its mild conditions to work and the possibility of using the sunlight.
In order to promote an effective practical depollution of outdoor/indoor atmospheres, new materials have been developed, through the creation of new modifications in their chemical structure (doping and defects), their morphology (0D, 1D, 2D and 3D systems), and hierarchical structure (hybrid composites, electronic heterojunctions, membranes, etc.). Thus, new or improved functionalities for the application of these systems as air purification photocatalysts have been created. In this sense, those are also applied as photocatalytic additives to build materials (ceramics, mortars, pavements, paints, etc.) and perform air-cleaning operations at urban centres.
Therefore, this Special Issue compiles the most important recent advances in photocatalytic materials for air purification and aims to act as a meeting forum for acknowledged experts in this field.

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. Catalysts 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 2700 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.
