Efficiency of a semiconductor catalyst is directly correlated to its surface to
which a reactant species is adsorbed. There are several ways to optimize the active
surface, such as synthesis, processing or any aftertreatment of a photocatalytic
material. Our research was focused on modifying the existing sonochemically
assisted synthesis of bismuth vanadate.
Two optimization methods were used in order to increase specific surface of the
photocatalyst and number of its active sites. The first method was to change
concentration of reactants used in the synthesis to reduce agglomeration of bismuth
vanadate. Sonochemically assisted synthesis was performed with three different
concentrations of reactants to observe agglomeration tendency of the catalyst. The
other method included the use of sodium dodecyl sulfate (SDS) as a surfactant in
synthesis at highest concentration in order to hinder the particle growth.
Bismuth vanadate was shown to degrade mordant blue 9 dye (MB9) most
...
effectively in alkaline medium (pH = 13) under visible light, discoloring the solution
in under 2 hours, while the highest adsorption of MB9 is observed in acidic solution
(pH = 1).
