Modification of TiO2 with clam-shell powder for photodegradation of methylene blue

The wide application of dyes has become the motivation of this research as significant amount of methylene blue (MB) in water portrayed potential risk to human well-being. Photocatalytic process is a promising yet sustainable method for the removal of dyes. In this study, clam shell (CS) powder has...

The wide application of dyes has become the motivation of this research as significant amount of methylene blue (MB) in water portrayed potential risk to human well-being. Photocatalytic process is a promising yet sustainable method for the removal of dyes. In this study, clam shell (CS) powder has been successfully loaded into TiO2 through hydrothermal method resulting in TiO2/Clam Shell powder composite (TiO2/CS) to improve the photodegradation performance of TiO2.

The loading of CS has enhanced the visible light absorption through lowering the bandgap energy of TiO2 from 3.0 to 2.2 eV and increases specific surface area of TiO2.
