摘　　要：过渡金属氧化物三氧化钼(MoO3)因其独特的结构和物理化学性质,一直以来是人们研究的热点。三氧化钼的结构目前已知的有3种:α-MoO 3、β-MoO 3和h-MoO3,其中α-MoO 3属于热力学稳定相,而β-MoO 3和h-MoO3属于热力学介稳相。介稳相比稳定相具有更多的物理化学活性。因此,寻求介稳相MoO 3简单、有效和快速的合成方法,探索其潜在的性能将具有更实际的意义。本文总结了近年来介稳相MoO 3的制备、性能和相关机理分析研究,展望了介稳相MoO 3的研究发展方向。Transition metal oxide molybdenum trioxide(MoO 3)has been a hot topic for research because of its unique structure and physicochemical properties.There are three known structures of molybdenum trioxide:α-MoO 3、β-MoO 3 and h-MoO 3,α-MoO 3 belongs to thermodynamic stable phase,whileβ-MoO 3 and h-MoO 3 belong to thermodynamic dielectric stable phase.The metastable phase has more physicochemical activity than the stable phase.Hence,it will be more practical to seek simple,efficient and fast synthesis method of metastable phase MoO 3 and explore its potential performance.This paper summarizes the preparation,properties and related mechanism analysis of metastable phase MoO 3 in recent years,and looks forward to the research and development direction of metastable phase MoO 3.
