英文摘要：

MoO3 has unusual layered structures or channels, in which some small molecules and ions can easily be inserted to forming MoO3-based compounds, and inherit the MoO3 crystal structure. It may be applied in many fields such as catalysis, optical/electrical, gas-sensor material, pigment and so on. The recent development of the preparation method, properties and potential applications are reviewed, and the future research and problems of the MoO3 and the MoO3-based compounds are prospected in this paper.
