Special Issue Information
Dear Colleagues,
With the gradual depletion of fossil fuels and deterioration of the ecological environment, it is necessary to pursue renewable and sustainable energy sources. Hydrogen (H2) has been considered as a clean and new energy due to its high energy density and negligible pollution of combustion products. Water electrolysis is deemed as a promising strategy to produce H2 because of abundance in resources and carbon-free emissions. However, the practical application of water splitting has been largely impeded due to the relatively slower kinetics and higher overpotentials of oxygen evolution reaction (OER) at the anode. In acid media, commercial Pt/C and RuO2 (IrO2) are regarded as the optimal electrocatalysts for hydrogen evolution reaction (HER) and OER, respectively, but their applications are limited by using a large number of noble metals. In alkaline media, non-noble metals for catalysts are easy to be obtained, but the kinetics of HER is sluggish, and overpotentials of OER are higher, too. Therefore, the development of high efficient and stable few-or free-noble metal electrocatalysts is important.
In this Special Issue, we invite investigators to contribute original research articles, communications, as well as review articles that are related to new materials design for HER and OER in acid or alkaline media.

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.
