摘要：

TiO2 nanoparticles were prepared using the hydrolysis of titanium tetraisopropoxide (TTIP) in W/O microemulsions consisting of water, nonionic surfactant and cyclohexane. The photocatalytic degradation of p-nitrophenol has been studied by using a batch reactor in the presence of UV light. The crystallite size and crystallinity increase with a decrease of hydrophilic group chain length and an increase of calcinations temperature. In addition, the photocatalytic activity increases with an increase of hydrophilic group length.
