Photo(electro)catalysis for Water Splitting

Dear Colleagues,

Water splitting via photoelectrochemical (PEC) technology is a viable method for producing hydrogen energy. The substantial recombination of photo-generated charges, the high overpotential, the slow rate of the surface reaction, and the oxygen-forming oxidation process all contribute to restricting the effectiveness of a photoelectrocatalytic (PEC) splitting of water. The search for inexpensive nano-metal oxides to produce hydrogen from water was particularly targeted because of the rarity of precious catalysts, the difficulty they encounter while functioning, their expensive nature, and the fact that they are unable to be applied on a large scale. Metal oxides are strong contenders, especially if they are well-synthesized and feature a large surface area, quick charging transport, many active sites, and large transport of ions. To give readers a thorough understanding of the state of the study area at this moment in time, this subject is devoted to both the fundamental and applied aspects of photoelectrocatalysis. This is anticipated to assist in closing the gap between the most basic understanding of hetero-junction photocatalytic systems and the creation of hydrogen-generating applications based on practical implementation that pave the way for new technologies and opportunities for future elimination of the mentioned obstacles.

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.
