Application


  • Tungstosilicic Acid: A Promising Electrolyte for Redox Flow Battery.: This study explores the use of tungstosilicic acid (TSA) as an electrolyte in redox flow batteries (RFB). The research highlights TSA′s high energy density due to its multi-electron transfer capability, making it a promising candidate for enhancing the efficiency and power density of RFBs. This advancement is particularly relevant for large-scale energy storage systems integrating renewable energy technologies (Sharma et al., 2023).

  • Heterogenization of a Tungstosilicic Acid Catalyst for Esterification of Bio-Oil Model Compound.: This paper explores the heterogenization of tungstosilicic acid by supporting it on silica-based materials for the esterification of bio-oil model compounds. The catalyst shows high activity and stability, indicating its potential for industrial applications in bio-oil upgrading (Prasertpong et al., 2022).
