Special Issue Information

Dear Colleagues,

We welcome your submission to this Special Issue, which is intended to collect a series of papers on the thematic issue of “Photo(electro)catalytic Water Splitting for H2 Production.”

The energy demand will increase with the increase in human population, and fossil fuels will not be able to fulfill this demand. Hydrogen is a promising alternative to unsustainable fossil fuels due to its vital role in ammonia and clean-burning fuel production. As we know, about 96% of the world’s hydrogen comes from the reformation of fossil fuels, which utilize high energy, followed by serious CO2 emissions. The biggest technological challenges towards realizing sustainable energy production are the development of new materials and devices, capable of harnessing and storing energy cleanly and sustainably. Efficient and sustainable hydrogen can be produced with the help of the state-of-the-art photocatalysis and Electrocatalysis from water splitting. Water Splitting is one of the most efficient and reliable approaches to produce hydrogen from renewable energy, such as solar, wind, and hydropower for large scale energy storage. This is an economically efficient way, where electrolysis of water can be achieved at room temperature, and the only required inputs are water and energy (electricity). The main challenge of water splitting is efficiency, stability, cheap earth-abundant catalyst, and the separation of H2 and O2 during the reaction. Development of efficient, cost-effective, and stable electrocatalysts for water oxidation is very useful in promising energy conversion technologies such as water electrolyzers, integrated solar water-splitting devices, and Li-based batteries. Water splitting is a combination of two half-reactions, where the oxygen evolution reaction (OER) and the hydrogen evolution reaction (HER) occur at the anode and cathode, respectively, of an electrochemical cell.

The vision of this Special Issue is to report novel catalysts for (photo) electrochemical conversion processes which can convert water into a high-value chemical product such as Hydrogen. We invite researchers to contribute review and original articles, which covers but not limited to the following topics.

  1. Computational Modelling of Catalysts for Water Splitting
  2. Reaction Mechanism of Oxygen Evolution Reaction & Hydrogen Evolution Reaction Catalysts
  3. 2D materials for Water Electrolysis
  4. Perovskites-based Photo or Electrocatalysts
  5. Metal oxides for Photoelectrochemical process
  6. Z-Scheme Heterojunctions-based Photo(electro)catalysts

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. Energies 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.
