Special Issue Information
Dear Colleagues,
Water electrolysis is the process of electrolyzing water (H2O) by employing a direct current to produce hydrogen and oxygen. Notably, due to its distinct feature of being pollution-free, hydrogen generation from water electrolysis is widely acknowledged as a sustainable technique for producing hydrogen. Unfortunately, the practical use of water electrolysis is constrained by the sluggish kinetics of the HER and OER. Currently, effective electrocatalysts are required to enhance the process, such as noble metals (Pt and Ir/RuO2). Nevertheless, the broad industrial use of hydrogen generation from electrolytic water is constrained by its high cost. Furthermore, despite significant advances in water electrolysis technology, industrial water electrolyzers are still confronting performance and durability challenges from key electrocatalysts. For the rational development of appropriate electrocatalysts, it is imperative to assess the performance of water electrolysis in industrial settings with various pH levels and high current densities.
This Special Issue concentrates on the design of electrocatalysts for electrolyzing water from the perspectives of physical chemistry and materials chemistry, such as electron orbitals, surface chemistry and nano-dimension. Moreover, experimental methodologies such as electron spectroscopy and spectroscopy with in situ observation and theoretical methods such as DFT calculation and molecular dynamic simulations are needed to explore the electrolysis reaction mechanism and ultimately realize a high-performance water electrolyzer.

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. Molecules 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.
