Description
Summary:The study considered the preparation and catalytic properties of the TiO2 particles supported on Date Stones Activated Carbon (TiO2/DSAC) and Polyvinyl Alcohol (TiO2/PVA). The prepared samples were characterized by different techniques. The photocatalyst obtained from DSAC support is better than the PVA one in a comparison of the physico-chemical properties, and was also confirmed by the photocatalytic degradation of Brilliant green (BG). The analysis results show that the TiO2 particles were well dispersed in the DSAC surface and the size of the resulting TiO2 crystallites reaches 18nm. The 24.7wt% of TiO2 were deposited on the activated carbon whereas 18.5wt% were agglomerated on the PVA surface. It was concluded that the higher photocatalytic activity in TiO2/DSAC was due to parameters such as content of carbon, percentage of anatase, number of hydroxyl groups and surface area of the catalyst.
