提出了利用简单的离子液体1-甲基-3-乙基-咪唑溴辅助水热法合成六方WO3纳米棒束的方法,对其结构进行了表征,并讨论其形成机理。TEM照片表明:WO3纳米棒束由长200～300 nm、直径25～30 nm的纳米棒组装而成。离子液体1-甲基-3-乙基-咪唑溴在纳米棒的形成过程中起到了结构导向剂的作用。
A simple ionic liquid 1-methyl-3-ethyl-imidazolium bromide hydrothermal method was proposed to synthesize hexagonal WO3 nanorod bundles. The structure was characterized and its formation mechanism was discussed. TEM images show that the WO3 nanorods are assembled from nanorods with lengths of 200-300 nm and diameters of 25-30 nm. The ionic liquid 1-methyl-3-ethyl-imidazolium bromide acts as a structure-directing agent in the formation of nanorods.
