Special Issue Information
Dear Colleagues,
The rapid growth of global energy consumption and related environmental issues has triggered an urgent need for renewable and clean energy. Clean and renewable hydrogen (H2), which can store energy from renewable sources such as sunlight and wind, is a promising candidate. Hydrogen has proven its potential as an ideal energy carrier for the sustainable energy economy thanks to its high energy density and eco-friendly production possibilities. Water electrolysis producing hydrogen provides a promising strategy for solving energy and environmental problems. Energy can be concentrated within chemical bonds via hydrogen evolution reaction (HER), which can then be released through the reverse reaction of the fuel cell on demand. The HER occurs at the cathode of the electrolysis water device. The occurrence of HER basically depends on the efficiency of the electrocatalyst, which requires stability and can quickly reduce water at a potential rate close to its thermodynamic value. Although precious metals (such as Pt, Ir RuO2 or IrO2) show high activity, they are severely limited due to their high cost and low abundance. Therefore, there is an urgent need to develop HER catalysts with efficient activity and long-term stability that are preferably based on earth-abundant elements. In addition, the membrane is the other key material for water splitting in basic electrolytes.

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.
