About this Research Topic

Manuscript Submission Deadline 05 December 2022

Electrocatalysis of small molecules such as hydrogen, nitrogen, oxygen, water, methanol, methane, carbon monoxide and carbon dioxide is essential for developing electrochemical energy conversion and storage technologies. Yet the state-of-art precious metal catalysts are limited by metal availability, price, activity, long-time stability, and selectivity. Hence, electrocatalysts with low or no precious metals should be elaborately designed to obstacle the sluggish kinetics or poor selectivity of electrocatalysis.

Low/non-precious metal-based materials (L/N-PMM) including metal-free carbon nanomaterials, transition metal-based nanomaterials, and low-precious-metals supported catalysts, are promising for electrocatalysis applications due to their abundant composite forms, regulatable structural/electron features, and potential performances. Thanks to the advantages of L/N-PMM, significant advances have been achieved by the balance of geometric and electronic structures of nanomaterials in the fields of fuel cells, metal-air batteries, water splitting devices, and supercapacitors. However, the precise design of L/N-PMM and the exploration of their catalytic mechanisms remain critical to advances in their application in energy conversion and storage.

This Research Topic aims to highlight Original Research, Review articles and Perspectives involving the design and applications of L/N-PMM for electrocatalysis. We especially welcome manuscripts discussing the structure-activity relationships and prospects of nanocatalysts to help design novel high-performance catalysts. Subjects covered may include, but are not limited to:

• Synthesis of low/non-precious metal-based nanomaterials, such as carbon-based materials, transition metal-based nanomaterials, atomic precious metal nanomaterials, precious metal nanoclusters;
• Applications in fuel cells;
• Applications in metal–air (oxygen) batteries;
• Applications in photo/electro water splitting;
• Applications in photo/electro CO2 reduction;
• Applications in photo/electro N2 reduction.

Important Note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.
