Special Issue Information

Dear Colleagues,

Electrocatalysis plays a key role in clean energy conversion, providing many sustainable green routes for future technologies via combining with renewable energy inputs. Low-dimensional nanomaterials toward advanced electrocatalytic application have stimulated interest due their unique chemical and electronic structures. The high structural tunability of low-dimensional nanomaterials offers new possibilities in electrocatalysis. Despite significant progress being made in recent decades, further in-depth study is still required to clarify how to develop high-performance electrocatalysts based on low-dimensional nanomaterials for different electrocatalytic reactions.

This Special Issue called “Low-Dimensional Nanomaterials for Advanced Electrocatalysis” aims to report the latest innovative research and development in this field, covering a broad of topics, including, but not limited to, the design, synthesis, and characterization of low-dimensional nanomaterials toward various electrocatalytic reactions (oxygen reduction reaction, hydrogen evolution reaction, oxygen evolution reaction, carbon dioxide reduction, ammonia synthesis, etc.).

We welcome contributions from all related groups.

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. Nanomaterials 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 2900 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.

Next-generation alkaline water electrolyzers will be based on zero-gap configuration to further reduce costs related to technology and to improve performance. Here, anodic porous transport layers (PTLs) for zero-gap alkaline electrolysis are prepared through a facile one-step electrodeposition of Ni,Fe,Co-based layered double hydroxides (LDH) on 304 stainless steel (SS) meshes. Electrodeposited LDH structures are characterized using Scanning Electron Microscopy (SEM) confirming the formation of high surface area catalytic layers. Finally, bi and trimetallic LDH-based PTLs are tested as electrodes for oxygen evolution reaction (OER) in 1 M KOH solution. The best electrodes are based on FeCo LDH, reaching 10 mA cm−2 with an overpotential value of 300 mV. These PTLs are also tested with a chronopotentiometric measurement carried out for 100 h at 50 mA cm−2, showing outstanding durability without signs of electrocatalytic activity degradation.
