Nanocomposites in Electrochemical Reactions: Catalytic Analysis and Applications

Dear Colleagues,

Electrochemical catalytic analysis using nanocomposites is advancing rapidly, driven by the development of innovative electrochemical techniques that allow for more precise and insightful evaluation of catalytic activity. New approaches such as in situ electrochemical impedance spectroscopy (EIS), cyclic voltammetry with operando spectroscopy, and advanced scanning electrochemical microscopy are enabling researchers to closely monitor reaction kinetics, charge transfer processes, and active site dynamics at the nanoscale. By applying these techniques to nanocomposites, which can be engineered for high surface area and tunable electronic properties, it becomes possible to identify optimal structural and compositional characteristics for specific catalytic reactions. These advancements are particularly impactful in applications like fuel cell technology, CO₂ reduction, and wastewater treatment, where improved catalytic efficiency and selectivity are essential. The combination of nanocomposites with cutting-edge electrochemical analysis not only enhances understanding of catalytic mechanisms but also paves the way for developing more sustainable and effective solutions in clean energy and environmental remediation.

This Special Issue on “Nanocomposites in Electrochemical Reactions: Catalytic Analysis and Applications” seeks high-quality contributions focusing on innovative techniques, applications, and theoretical insights. Topics of interest include, but are not limited to, the following:

• Development and application of novel electrochemical techniques for analyzing catalytic processes in nanocomposites.
• In situ and operando methods for real-time monitoring of catalytic reactions at nanoscale interfaces.
• Design and synthesis of nanocomposites with enhanced electrochemical properties for catalytic applications.
• Mechanistic studies of catalytic reactions facilitated by nanocomposites, with emphasis on active site dynamics and reaction pathways.
• Theoretical modeling and computational approaches, including density functional theory (DFT), to predict and optimize catalytic performance.
• Construction of free energy diagrams to elucidate reaction mechanisms and identify rate-determining steps.
• Simulation of electronic structure and charge transfer in nanocomposites to guide catalyst design.
• Application of nanocomposite catalysts in sustainable energy technologies, such as hydrogen evolution, oxygen evolution/reduction, and alcohol oxidation/CO₂.
• Electrochemical detection and degradation of pollutants using nanocomposite-based catalysts in environmental remediation.
• Integration of nanocomposites in electrochemical sensors and biosensors for enhanced sensitivity and selectivity.
