Special Issue Information

Dear Colleagues,

Hydrogen energy, as an efficient, clean and sustainable "carbon free" energy is of great significance to the sustainable development of human society. Among several hydrogen production technologies, photo(electric) hydrogen production has attracted much attention because its energy comes from abundant solar energy and electric energy converted by solar energy, potentially solving the energy crisis and avoiding environmental pollution caused by traditional fossil energy hydrogen production. Initially, the efficiency of the hydrogen production process is rather limited, which mainly results from the existing drawbacks of catalysts such as instability and low activity. Here, it is of great value to evaluate  the photo(electric) hydrogen production system, engineering electrodes with advanced materials, the parameters in water oxidation reactions occurring on the surface of anodes, and the basic functions of co-catalysts on the promotion of electrocatalyst, photoelectrocatalyst, and photocatalyst performance. We welcome colleagues in the field of photo(electro)catalysis to submit your original research articles and review articles.

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.

The manipulation of trap states plays a crucial role in the development of efficient photocatalysts. An ultrathin-shelled Zn-AgIn5S8/ZnS quantum dots (QDs) photocatalyst was synthesized via in situ growth using a low-temperature hydrothermal method.

The manipulation of trap states plays a crucial role in the development of efficient photocatalysts. An ultrathin-shelled Zn-AgIn5S8/ZnS quantum dots (QDs) photocatalyst was synthesized via in situ growth using a low-temperature hydrothermal method. The optical properties of the samples coated with ZnS shell were studied vis UV-vis absorption and fluorescence spectra. The ultrathin ZnS shell plays an important role in the Zn-AgIn5S8/ZnS core–shell heterostructure photocatalytic water splitting system, which could reduce surface defects, prolong the carrier lifetime and improve the photo-generated electron–hole pair separation effectively, resulting in the improved photocatalytic efficiency and enhanced stability of the catalyst. The results provide an effective guideline for shell thickness design in future constructions of the core–shell heterostructure photocatalyst. Full article

As non-noble metal co-catalysts, Nitrides have received extensive attention for their high efficiency and low cost in photocatalytic hydrogen production. In this study, we develop a novel composite co-catalyst of Au/Ta3N5 that significantly enhanced the photocatalytic hydrogen production activity of CdS. The activity of photocatalyst (Au/Ta3N5)/CdS is 7.3 times of bare CdS and 2.2 times of Ta3N5/CdS. The proper capacitance and enhanced activity of Ta3N5 demonstrates the capacitance catalysis effect of Ta3N5, which improves the charges separation and storing of the photoexcited electrons from CdS. Au acts as an active site for proton reduction to further improve the activity. Full article
