초록

The hybrid $C/TiO_2$ complexes were prepared by a method involving the penetration of titanium n-butoxide (TNB) solution with porous carbons. The photocatalysts were investigated for their surface textural properties and SEM morphology, structural crystallinity and elemental identification between porous carbon and $TiO_2$, and dye decomposition performance. For all the $C/TiO_2$ complexes prepared by TNB solution methods, the excellent photocatalytic effect for dye degradation should be attributed to the synergitic effects between photo-decomposition of the supported $TiO_2$ and adsorptivity of the porous carbons.
