Special Issue "Bimetallic Photocatalysts"
Deadline for manuscript submissions: 30 September 2020.
Interests: inorganic and organic nanomaterials, hybrid nanoparticles, high-resolution transmission electron microscopy, nanomaterials for catalysis, molecular dynamics
The photocatalytic activity of well-known catalysts can be successfully tuned by modifications using various types of metallic elements. One of the most promising approaches is the utilization of bimetallic systems to significantly improve the catalytic efficiency as well as to reduce the cost of application of such systems, making them more competitive with other widespread materials. Nanoparticles composed of two different metallic elements show novel electronic, optical, catalytic, or photocatalytic properties compared with their monometallic counterparts. The aim of many studies taking the advantage of bimetallic materials is to expand the absorption of photocatalysts towards the visible region of light. In the case of plasmonic bimetallic nanoparticles deposited on a semiconductor surface, they may enhance the photocatalytic activity under UV and visible light irradiation. Although the effect of monometallic particles on the photocatalytic activity of a semiconductor is well investigated and proved, the influence of the structure and composition of bimetallic materials on the photocatalytic reaction still needs a detailed clarification.Dr. Grzegorz Nowaczyk
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. Materials 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 2000 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.
