Photocatalysts for Efficient Removal of Dyes from Industrial Effluents: Prospects and Challenges

Dear Colleagues,

Photocatalysis is a promising green, clean and environmentally friendly technology with low energy consumption developed in recent years for the treatment of industrial wastewater. Organic dyes constitute one of the largest groups of wastewater pollutants. The synergistic effects of adsorption and visible light catalysis significantly enhance the removal of dyes. In this regard, various environmentally friendly materials have been synthesized possessing unique benefits such as superior efficiency and selectivity, good recyclability, a low cost and stability for the efficient photodegradation of organic dye species by advanced oxidation processes.

This Special Issue will focus on photocatalysts for the efficient removal of dyes from industrial effluents. The perspectives and challenges generated by various photocatalytic materials, dyes and mechanisms of degradation processes will be evaluated. Thus, the synergic effect of dye adsorption on the efficiency of various high-surface-area photocatalysts such as semiconductors, supported metals/oxides, composites and carbonaceous and hybrid mesoporous materials will be evidenced. The properties of the polluting dyes from industrial effluents and their degradation mechanisms in conditions of various photocatalysts and light irradiations along with the future prospects of highly adsorptive photocatalytic materials and their application in the photocatalytic removal of dyes from wastewater will be evidenced as well.

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 250 words) can be sent to the Editorial Office for assessment.

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 2200 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.
