Non-Noble Metal Electrocatalysts for Electrochemical Energy Storage and Conversion

About this Research Topic

With the increasing concerns of rapid fossil fuel depletion and environmental pollution, numerous efforts have been devoted to search for sustainable alternative energy. Clean and renewable energy technologies, such as fuel cells, metal-air batteries, water electrolysis and carbon/nitrogen fixation, shows great promise toward solving current energy and environmental challenges. Among these clean technologies, a series of electrochemical reactions play a crucial role and dominate the overall system efficiency, including oxygen reduction reaction (ORR), oxygen evolution reaction (OER), hydrogen evolution reaction (HER), carbon dioxide reduction reaction (CO2RR), nitrogen reduction reaction (NRR) and small organic molecules (methanol, ethanol, formic acid, urea) oxidation reactions, etc. However, these key reactions always possess sluggish kinetics, thus necessitating efficient electrocatalysts to expedite the reaction rate. At present, noble metal-based materials are commonly identified as the benchmark electrocatalysts with high activity (e.g., Pt-based materials for ORR and HER, Ru/Ir-based materials for OER, and Au-based materials for CO2RR and NRR), but the high cost, scarce reserves and poor long-term stability have seriously hindered their large-scale commercialization in practical energy devices. Therefore, it is highly desirable to develop alternative non-noble metal electrocatalysts that are readily available, cost-effective, and possess catalytic performance comparable to (or even higher than) noble-metal-based electrocatalysts.

This Research Topic aims to collect latest advancements in the design of advanced non-noble metal materials, including metals/alloys, metal oxides (hydroxides), metal phosphides/sulfides/selenides/carbides/nitrides, single atoms, functional carbon materials, hybrids, etc, and their applications to electrocatalytic reactions, with special emphasis on designed strategies for promoting performance and property-activity correlation.
We welcome the submission of Original Research papers, Reviews and Perspectives on themes which may include, but not limited to:
• Novel synthesis and design of non-noble metal materials for energy-related electrocatalytic reactions (e.g., ORR, OER, HER, CO2RR, NRR, and other small organic molecules oxidation reactions).
• Optimization of structure, composition, morphology for boosted catalytic performance.
• New understanding of electrocatalytic mechanisms based on theoretical and experimental approaches.
• Potential application of non-noble metal materials in practical energy devices, including fuel cells, metal-air batteries, water electrolysis, and carbon/nitrogen fixation, and solid oxide electrochemical cells, etc.


Keywords: Metal oxides, Electrocatalysis, Electrochemistry, Material design, Energy conversion and storage
