Special Issue Information

Dear Colleagues,

Fossil fuels, e.g., coal, oil and gas, are important carbon carriers in the long-term carbon cycle, and were literately derived from renewable energy, solar energy, by the growth and burial of organic matters on Earth over a geological timescale. Artificial interference with the carbon cycle using cutting-edge technologies appears to be feasible, resulting in a very short cycle, aiming at zero emissions. Semiconductor-based photocatalysis has profoundly extended solar energy utilization to chemical production processes, where solar fuels emerge, via either water splitting for hydrogen production or CO2 reduction for hydrocarbon formation. Key challenges remain, particularly in terms of catalyst materials, i.e., semiconductor photocatalysts. This Special Issue therefore collects original research papers, reviews and commentaries on the rational design, synthesis, characterization, computational studies, and performance evaluation of catalyst materials, including semiconductors and co-catalysts, in either homogeneous or heterogeneous forms, for solar fuel production. Perspectives on the feasibilities of solar fuels are also welcome.

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 1600 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.

Hydrogen and hydrogen peroxide have been photoelectrocatalytically produced by electrocatalytic reduction using simple carbon electrodes made by depositing a mesoporous carbon film on carbon cloth. Visible-light-absorbing photoanodes have been constructed by depositing mesoporous CdS/TiO2 or WO3 films on transparent fluorine-doped tin oxide (FTO) electrodes. Both produced substantial photocurrents of up to 50 mA in the case of CdS/TiO2 and 25 mA in the case of WO3 photoanodes, and resulting in the production of substantial quantities of H2 gas or aqueous H2O2. Maximum hydrogen production rate was 7.8 µmol/min, and maximum hydrogen peroxide production rate was equivalent, i.e., 7.5 µmol/min. The same reactor was employed for the production of both solar fuels, with the difference being that hydrogen was produced under anaerobic and hydrogen peroxide under aerated conditions. The present data promote the photoelectrochemical production of solar fuels by using simple inexpensive materials for the synthesis of catalysts and the construction of electrodes. Full article
