Special Issue Information

Dear Colleagues,

In recent years, photocatalysis has boosted its contribution and relevance in multiple societal challenges related with environmental (water and air purification), energetic (generation of fine chemicals or clean fuels) or biological issues, to name a few. A vast number of publications, reviews, and Special Issues (including in this journal: http://www.mdpi.com/journal/catalysts/special_issues) have been published and devoted to the use of semiconductors and other materials as catalyst for those photocatalytic reactions. Nevertheless, the margin for further development is still wide open. This Special Issue aims at highlighting the most recent breakthroughs and discoveries carried out in this hot field with an especial emphasis on the advances made in the synthesis of photocatalysts based on carbon nanostructured supports (i.e., CNTs, C3N4, graphene, RGO, etc.) or that alternatively combine the use of conventional semiconductor supports with carbon nanostructures acting as sensitizers (i.e., carbon dots, graphene dots, carbon layers, etc.) to expand the photoresponse towards the visible-near infrared (NIR) range to enhance their photo-response in the visible-near infrared range. Special attention will be also devoted to noble-metal based photocatalysts capable of absorbing light in this same visible-NIR ranges that constitute themselves as plasmonic photocatalysts or can act as sensitizers. The application of these photocatalytic materials towards less explored reactions such as gas phase or in situ biophotocatalytic processes will be also especially welcome in this Special Issue. Additional information on previous Special Issues, launched by the the journal, can be found at http://www.mdpi.com/journal/catalysts/special_issues.

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 papers will be 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 1300 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.

Carbon-modified titania (C–TiO2) films were easily prepared by using an impregnation process with a glucose-containing TiO2 sol. Through controlling calcination conditions, the as-obtained C–TiO2 products exhibited highly photocatalytic activity for the degradation of gaseous NOx under visible light and ultraviolet illumination. The effects of carbon content and calcination temperature on the photocatalytic performances and their photochemical and physical properties were investigated. Carbonaceous species on the TiO2 surface enhanced the visible-light absorption of TiO2 films; however, an excessive amount of carbon on the TiO2 surface reduced its photocatalytic ability due to the serious coverage effect on active sites. The results show that a suitable glucose addition is about 50–100% of the weight of TiO2 content and the optimized calcination temperature is 300 °C, which leads to better photocatalytic activity under ultraviolet and visible- light irradiations. Accordingly, the simple-prepared C–TiO2 films functioned as visible-light-responsive catalysts, allowing for a feasible producing route for real applications. Full article
