Many intriguing ways have been identified to mitigate the low photocatalytic activity
of Titanium dioxide (TiO2). One of the ways is to adulterate the structure of TiO2
with foreign substances like metals i.e., Ni2+, Zn2+, Cr3+ and Fe3+, which are having
similar radii with Ti4+. In this study, the introduction of silver into the structure
of TiO2 by Liquid Impregnation (LI) method with various mole fractions have been presented.
Comparison has been made to degrade one model pollutant: Direct Blue 71 (DB71) by
using both doped and undoped TiO2. Study was further supported by studying the Langmuir
and Freundlich isotherms. Enhancement in the photocatalytic degradation of the dye
was observed with silver doped TiO2 at 2.0% mole fraction as compared to undoped TiO2.
While studying the photoctalytic activity, the reaction mixture pH was kept unchanged
with doped TiO2, wherein with undoped TiO2 demanded acidic pH to have more photocatalytic
activity.
