Photocatalysts for Hydrogen Evolution Reaction Based on ZnIn₂S₄ Materials

Dear Colleagues,

Photocatalytic hydrogen production is the best means available presently for human beings to obtain energy, but the important problem in this field is how to build highly active and low-cost photocatalysts. In recent years, the typical ternary metal sulfide of two-dimensional (2D) ZnIn₂S₄ nanosheets has been widely used in the photocatalytic field owning to its chemical stability, strong visible light absorption, and suitable band gap. Unfortunately, single-phase ZnIn₂S₄ nanosheets commonly exhibit serious agglomeration during the reaction process and tend to present a micro-flower structure composed of nanosheets, which seriously affects their photocatalytic activity due to the cover of active sites, limiting the effective use of photocarriers. Among enormous modification methods, construction of heterojunction/homojunction between g-ZnIn₂S₄ and other semiconductor photocatalysts with an interleaved energy band position is an effective channel to improve photocatalytic activity, which can be attributed to the accelerated photon-generated carrier transfer rate. This Special Issue will present the most recent and significant developments in highly efficient ZnIn₂S₄-based photocatalysts for hydrogen evolution reaction, where such systems are widely used. Original papers on the above topics and short reviews are welcome for submission.

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-anonymized 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.
