Hydrogen Evolution Reaction Mechanism at Nanoscale

Dear Colleagues,

Hydrogen, as a clean and sustainable energy carrier, plays a pivotal role in the global pursuit of net-zero emissions. The hydrogen evolution reaction (HER) is a critical component in the production of hydrogen, which involves the reduction of protons to molecular hydrogen. Despite its importance, the HER is often limited by high overpotential and sluggish kinetics, necessitating the development of efficient and cost-effective electrocatalysts. Therefore, it is very important to study the mechanism of HER to achieve efficient hydrogen evolution. Recently, nanoscale catalysts have received extensive attention in the field of HER, such as single-atom catalysts (SACs), quantum dots (QDs), metal–organic frameworks (MOFs), covalent organic frameworks (COFs), graphene, graphdiyne, et al. Furthermore, bandgap engineering, interface engineering, and other decoration strategies of the above catalysts also play a crucial role in modulating electronic structures and improving catalytic activity.

In this Special Issue of Nanomaterials, we aim to present the latest advancements in the understanding and applications of nanoscale mechanisms in the HER. We invite contributions from leading researchers in the field to share their insights on the design, synthesis, and performance of advanced catalytic nanomaterials. Topics of interest include the fundamental mechanisms of HER at the nanoscale, the role of heterostructured interfaces, and the development of novel catalysts for efficient hydrogen production and the applications of hydrogen.

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. Nanomaterials is an international peer-reviewed open access semimonthly journal published by MDPI.
