A research has been conducted with the title Photocatalytic Activity of Bentonite-TiO2 on Photodegradation of Methylene Blue Dyes. Which aims to determine the effect of the bentonite-TiO2 composite on the degradation process of methylene blue. In this study, a bentonite-TiO2 composite was made by impregnating TiO2 metal at bentonite. Bentonite-TiO2 was then characterized using XRD and SEM-EDX. …
