Visible Light Active WO3/TiO2 Heterojunction Nanomaterials for Electrochemical Sensor, Capacitance and Photocatalytic Applications

K. Gurushantha et al.

Summary: Developing a low-cost high-efficiency photocatalyst is of great importance in research. WO3:TiO2 (1:2 to 1:8) photocatalysts were synthesized using the ultra-sonication-assisted co-precipitation method for sensing heavy metal ions and degrading reactive blue 4 dye under visible light. The synthesized material was characterized through various techniques, and WO3:TiO2 (1:6) showed the best results. It also exhibited potential as a capacitor with a capacitance value of 24.7 x 10(-2) F/g.

Acid substitutions for WO3 nanostructures synthesis by the hydrothermal route and its effect on physio-chemical and electrochemical properties for supercapacitors

Umesh V. Shembade et al.

Summary: In this study, a feasible and eco-friendly electrode material for supercapacitor application was developed by synthesizing different morphological structures of tungsten oxide nanostructures (WO3NSs). The electrochemical activity of WO3-NSs was evaluated by employing concentrated acids in the synthesis process. The WO3-NSs exhibited different morphologies such as hexagonal-shaped nanosheets, one-dimensional nanorods, and heterogeneous non-uniform agglomerated nanosheets as observed by FE-SEM. The optimized WO3NRs were further characterized using TEM and XPS for detailed morphological, structural, elemental composition, and electronic states analysis. The electrochemical properties of the WO3-NSs were examined in 1 M KOH electrolyte, and the M-WO3-NF electrode showed high specific capacity, gravimetric capacitance, energy density, power density, and Columbic efficiency, as well as excellent capacitive retention over 5000 cycles.

Summary: WO3 coated on graphite showed improved capacitive performances when deposited by continuous electrodeposition method. The presence of CNW greatly enhanced the capacitance of WO3-based electrodes, while the presence of rGO had a less significant impact. These results suggest WO3/CNW/G electrode is recommended for supercapacitor applications.

Bon-Ryul Koo et al.

Summary: The newly synthesized low-temperature a-quantized WO3·H2O films show promising performance in EC energy storage devices, improving transmittance and specific capacitance. By inducing quantization of a-WO3, the films increase the number of electroactive sites, provide abundant oxygen vacancies, widen the band gap, and stabilize the structure with intercalated water molecules, resulting in efficient charge transfer and stress alleviation.
