Deposition of Activated Carbon/TiO2 on Polystyrene Polymer and Its Performance in Photodegradation of Methylene Blue

Oleh: Arsyad, Ya' muhammad, Wahyuni, Dwiria

Activated carbon (AC) combined with TiO2 photocatalyst can be used as a hybrid material in water purification. However, the dispersed–composite of AC/TiO2 in water needs additional treatment to obtain clean water, so it is considered less effective. This study aims to deposit AC/TiO2 on polystyren...
