摘要：

Nanostructured hollow titania has been synthesized by a facile hydrothermal method in water/2-propanol mixed solution. The synthesized hollow titania is of anatase phase with a novel worm-like morphology. The wall thickness of this hollow structure can be conveniently controlled from about 100 nm to 380 nm and the inner cavity diameter from 300 nm to 130 nm by changing the water to 2-propanol ratio. The formation of the hollow worm-like titania could be attributed to the microheterogeneity of the water/2-propanol system. Furthermore, the as-synthesized product exhibits higher photocatalytic activity than that of commercial P25 in the methylene blue (MB) degradation reaction. (C) 2010 Elsevier B.V.
