Synthesis, Characterization and Photocatalytic Activity of Bismuth Doped Titanium Dioxide under Different Light Sources
Abstract: 800x600 Photocatalysis is a recognized approach where light energy is employed to excite the semiconductor material and produce electron-hole pairs. These electron-hole pairs eventually involves in the detoxification of pollutants (in air or water) & water splitting. TiO2 photocatalyst shows poor activity in visible light due to its wide band gap (3.2 eV), which restricts its use under Sun light. In the present work, photocatalytic activity of TiO2 was enhanced …
