Impact of chitosan on CS/TiO2 composite system for enhancing its photocatalytic performance towards dye degradation

Chitosan, supported by titanium dioxide nanocomposite (CS/TiO2) is synthesized using the in-situ sol-gel method. The synthesis was carried out at room temperature to obtain CS/TiO2 containing TiO2 in the anatase phase. The prepared samples were characterized by using scanning electron microscopy, X-...
