Abstract
Synthesis of a ZnO/montmorillonite photocatalyst based on an Indonesian natural montmorillonite was conducted using a sol–gel intercalation method. The physicochemical properties of the material were determined by XRD, N2 adsorption–desorption, SEM, TEM and UV–Vis diffuse reflectance. The activity was evaluated in photocatalytic and photochemicaldegradation of methyleneblue (MB) with and without H2O2. Characterization showed that the ZnO particles were successfully distributed in montmorillonite support and ZnO/montmorillonite had lower band gap energy. The increased adsorption of MB on ZnO/montmorillonite resulted in faster photodegradation. The kinetics of the reaction obeyed the Langmuir–Hinshelwood model.
