摘要：
Hydrothermally grown monoclinic tungsten trioxide on fluorine-doped tin dioxide glass substrates was performed using an aqueous solution of tungsten trioxide in powder form adjusting the pH through HCl for various growth periods at 95 °C. Enhanced crystalline quality oxide coatings were obtained using HCl concentration of 6 M for 24 h. These samples exhibited large crystallites consisting of agglomerated nanoparticles. It has been found that they presented an intercalated charge storage capability of 3.97 C cm−2 with a respective capacitance of 197.5 F g−1. The importance of achieving crystalline low-cost tungsten trioxide with enhanced electrochemical performance is highlighted.
