Metal Catalysts for Heterogeneous Catalytic Reactions

Dear Colleagues,

Hydrogen energy is known as the next generation of secondary clean energy, but the cost of hydrogen preparation has always been a bottleneck hindering the large-scale application of hydrogen energy, especially green hydrogen production. While hydrogen fuel can be produced in a more environmentally friendly way through the electrolysis of water, fossil fuels are still currently used in the hydrogen-powered production chain. Therefore, the energy used for hydrogen fuel production must be produced using green technologies to ensure that hydrogen fuel vehicles are considered a better environmental choice. Water molecules are a very abundant source of green hydrogen, and thus determining a way to make the hydrogen extraction reaction from water happen at a lower temperature with high efficiency has always been a challenge for researchers worldwide.

At present, the universal catalyst for hydrogen production in electrolyzed water is Pt/C, but its cost is high and it is difficult to apply on a large scale. Preparing high-performance, high-stability catalysts with inexpensive non-precious-metal catalysts is a challenge. Aiming at the major strategic goals of energy and the environment, it is necessary to deeply explore the relationship between the structure and performance of heterogeneous metal catalysts to develop new catalytic materials, from exploring key scientific issues to solving practical application problems. For this Special Issue of Metals, we welcome reviews and articles on the principles, theoretical calculation, material preparation and characterization, and applications of hydrogen metal catalysts.

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 250 words) can be sent to the Editorial Office for assessment.

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. Metals 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 2600 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.
