摘要：

Nanocrystalline TiO2 is prepared using a stearic acid gel method. Their surface state is analyzed by means of X-ray photoelectron spectroscopy (XPS). The photocatalytic degradation of methyl orange in TiO2 suspension is investigated. The relationships between surface state and photocatalytic activity are discussed. (C) 2001 Elsevier Science B.V.
