Uniform carbon-covered titania and its photocatalytic property

Carbon-covered titania (CCT) was prepared via pyrolysis of sucrose highly dispersed on the surface of titania. The as-prepared CCT shows much higher catalytic activity for MB's photodegradation than pure titania under UV illumination. In addition, MB can be decomposed over CCT under visible light illumination, whereas it is simply bleached over pure titania at the same condition.
