Special Issue Information

Dear Colleagues,

Artificial photocatalysis is deemed one of the most promising pathways for mitigating environmental contamination and the energy dilemma caused by the rapid development of modern technology. Versatile polymers nowadays play an increasingly important role in the design of photocatalysts due to their various merits, including their cost-effectiveness, functionality and structural tunability.

This Special Issue aims to cover all polymeric materials designed for photocatalysis, which mainly consist of the following three types: (1) polymers with semiconducting behaviors, which can drive photocatalytic reaction themselves, such as carbon nitride (g-C3N4), conjugated polymers and covalent organic frameworks (COFs); (2) conducting polymers, which can accelerate photo-excited charge transfer, such as polypyrrole (PPy) and polyaniline (PANI); and (3) polymers that act as assistants or substrates, which can tailor the physicochemical properties of photocatalysts or transform photocatalyst powders into monoliths with various shapes and sizes (e.g., films, gels), such as cellulose, chitin and chitosan.

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. Polymers is an international peer-reviewed open access semimonthly 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.

In this study, a novel direct Z-scheme SnS2 quantum dots/sulfur-doped polyimide (SQDs/SPI) photocatalyst was firstly fabricated by an in situ crystallization growth of SnS2 quantum dots on sulfur-doped polyimide through a facile hydrothermal method. The photocatalytic hydrogen production activity of 5SQDs/SPI samples reached 3526 μmoL g−1 in the coexistence of triethanolamine and methanol used as hole sacrificial agents, which is about 13 times higher than that of SPI under the same conditions and 42 times higher than that of SPI only as a hole sacrificial agent. The improvement can be related to the direct Z-scheme charge transfer in the tight interface between SQDs and SPI, which promoted rapid separation and significantly prolonged the lifetime of photoexcited carriers. The Z-scheme charge transfer mechanism was proposed. This discovery comes up with a new strategy for the development of an efficient, environmentally friendly, and sustainable sulfide quantum dots/polymer non-noble metal photocatalyst. Full article
