Next-Generation Nanomaterials for Electrocatalysis and Energy Storage

Dear Colleagues, 

The global transition towards sustainable energy and chemical economies hinges on critical breakthroughs in electrocatalysis and energy storage technologies. While significant progress has been achieved, current systems often face limitations in efficiency, cost, durability, and nanomaterials sustainability. This Special Issue of Nanomaterials, entitled "Next-Generation Nanomaterials for Electrocatalysis and Energy Storage", is dedicated to showcasing the latest advancements in the design, synthesis, characterization, and mechanistic understanding of novel nanomaterials poised to overcome these challenges. This Issue will highlight innovative nanomaterials strategies that push the boundaries of performance in key electrochemical reactions and energy storage devices, paving the way for a cleaner and more energy-secure future. We aim to bring together cutting-edge research and insightful reviews that explore the frontiers of nanomaterials science in these vital fields, welcoming both original research articles and comprehensive review articles. Contributions are invited on topics including, but not limited to, the following areas: 

1.1 Novel Electrocatalyst Design: 

• Articles may discuss the synthesis, characterization, and performance of advanced electrocatalysts, including single-atom catalysts (SACs), high-entropy alloys/oxides/nitrides, metal–organic frameworks (MOFs), covalent organic frameworks (COFs), MXenes, nanostructured carbons, metal-free catalysts, and quantum dots. 

1.2 Nanomaterials Development for Enhanced Electrocatalytic Reactions: 

• Hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) for efficient water splitting. 
• Oxygen reduction reaction (ORR) for fuel cells and metal–air batteries. 
• CO₂ reduction reaction (CO2RR) for valuable fuels and chemicals. 
• Nitrogen reduction reaction (NRR) for sustainable ammonia synthesis. 
• Electrocatalytic oxidation/valorization of biomass, alcohols, and other organic molecules. 

1.3 Mechanistic Insights: 

We welcome studies focusing on understanding reaction mechanisms, identifying active sites, and catalyst stabilization using advanced in situ/operando characterization techniques and computational modeling. 

2.1 Advanced Battery Systems: 

• Nanomaterials for beyond lithium-ion batteries: anodes, cathodes, and electrolytes for sodium-ion, potassium-ion, magnesium-ion, calcium-ion, zinc-ion, and aluminum-ion batteries. 
• Solid-state batteries: development and understanding of novel solid electrolytes (e.g., sulfide, oxide, polymer, composite), interfacial engineering strategies (electrode-electrolyte), and all-solid-state cell performance. 

2.2 High-Performance Lithium-based Batteries: 

• Innovations in silicon anodes, lithium metal anodes (and their protection), advanced high-voltage/high-capacity cathodes, novel liquid and quasi-solid electrolytes, and functional electrolyte additives. 
• Nanomaterials and system design for lithium–sulfur and lithium–air batteries. 
• Supercapacitors and Hybrid Devices: 
• Novel electrode nanomaterials (e.g., MXenes, 2D nanomaterials, advanced porous carbons, pseudocapacitive metal oxides/sulfides/nitrides) for high-energy and high-power-density supercapacitors. 
• The development of advanced electrolytes for supercapacitors, including ionic liquids, redox-active electrolytes, and solid/gel electrolytes. 
• Nanomaterials for hybrid ion capacitors and other emerging electrochemical energy storage devices. 

2.3 Safety and Durability: 

Nanomaterials-focused approaches to enhance the safety, thermal stability, and cycle life of energy storage systems. 

• AI and Machine Learning in Nanomaterials Discovery: The application of artificial intelligence, machine learning, and high-throughput computational screening for the rational design, prediction, and discovery of novel electrocatalytic and energy storage nanomaterials. 
• Advanced Characterization and Modeling: The utilization of cutting-edge in situ/operando techniques (e.g., synchrotron-based methods, advanced microscopy, spectroscopy) and multiscale modeling to probe nanomaterials structures, interfaces, and dynamic processes during operation. 
• Sustainable Nanomaterials and Processes: The development of eco-friendly nanomaterials, green synthesis routes, and scalable manufacturing techniques for next-generation electrocatalysts and energy storage components. 
• Interfacial Science and Engineering: Fundamental studies and innovative strategies for understanding and optimizing interfaces (solid-solid, solid-liquid) in electrocatalytic systems and energy storage devices. 
• Defect Engineering and Nanostructuring: Tailoring nanomaterial properties through controlled introduction of defects, doping, strain engineering, and advanced nanostructuring techniques.
