Photodegradation kinetics of MB using either Degussa TiO2 at 340 nm (open circles) and 405 nm (filled circles) or CdSe/TiO2 core-shell nanoparticles at 340 nm (open square) and 405 nm (filled square). The lines represent first-order exponential kinetics. Control experiments without any photocatalyst at 340 nm (open triangle) and 405 nm (filled triangle) are also shown.
