Special Issue Information
Dear Colleagues,
Photocatalysis, which converts solar energy into reactive oxygen species, is considered to be a promising technology for alleviating environmental pollution and addressing energy issues. Nevertheless, traditional photocatalysts, such as TiO2 and ZnO, are limited to low solar energy utilization efficiency, slow photogenerated carrier separation rate and fast charge carrier recombination rate. It is of great importance to improve the utilization of solar photons and boost the spatial separation and migration of photoinduced carriers.
Carbon quantum dots (CQDs), a kind of zero-dimensional carbon-based nanomaterials, are considered biocompatible organic quantum dots with low toxicity and chemical stability. Additionally, the conjugated bonds in CQDs can promote electron storage and transfer. Therefore, CQDs can be employed to improve the photocatalytic performance of the photocatalyst.

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.
