The Application of Nanoscale Materials in Batteries, Sensors and Supercapacitors (2nd Edition)

Dear Colleagues,

In recent years, various nanomaterials have been extensively studied for application in charge storage and sensors due to their high performance, large surface area and special morphology, as well as unique properties. They can then present many new features for energy-storage devices and sensors, such as small and thin sizes, a long cycle life, high sensitivity, and a large energy density. A wide variety of novel energy storage devices, sensors, biosensors and supercapacitors are developed via the enhancement of nanomaterials.

This Special Issue of Nanomaterials entitled “The Application of Nanoscale Materials in Batteries, Sensors and Supercapacitors” aims to present state-of-the-art technology in the field of nanoscaled materials. Research from both traditional and interdisciplinary fields is welcome. Potential topics include, but are not limited to, the following:

• Novel fabrication methods for nanomaterials and composites;
• Modification, functionalization and doping of nanomaterials;
• Advanced characterization techniques;
• Assembly and processing of nanomaterials;
• Various composites containing different nanomaterials;
• Advanced batteries;
• Electrolytes;
• All kinds of sensors using nanoscale materials;
• Supercapacitors;
• Unique electrodes containing nanoscale material.

Abstract: The development of high-performance hydrogen peroxide (H2O2) sensors is critical for various applications, including environmental monitoring, industrial processes, and biomedical diagnostics. This study explores the development of efficient and selective H2O2 sensors based on bismuth oxide/bismuth oxyselenide (Bi2O3/Bi2O2Se) nanocomposites. The Bi2O3/Bi2O2Se nanocomposites were synthesized using a simple solution processing method at room temperature, resulting in a unique heterostructure with remarkable electrocatalytic properties for H2O2 detection. Characterization techniques, including X-ray diffraction (XRD), Raman spectroscopy and electron microscopy, confirmed the successful formation of the nanocomposites and their structural integrity. The synthesis time was varied to obtain the composites with different Bi2O2Se content. Electrochemical measurements revealed that the Bi2O3/Bi2O2Se composite formed under optimal synthesis conditions displayed high sensitivity and excellent selectivity towards H2O2 detection, along with a wide linear detection range and low detection limit. The superior performance is attributed to the synergistic effect between Bi2O3 and Bi2O2Se, enhancing electron transfer and creating more active sites for H2O2 oxidation. These findings suggest that Bi2O3/Bi2O2Se nanocomposites hold great potential as advanced H2O2 sensors for practical applications.
