Abstract: A method for preparing stannic oxide hollow nano material, relating to the nano material prepartion, especially relating to a method for preparing stannic oxide hollow nano material by taking zinc oxide as mould, and providing a general method for preparing stannic oxide hollow nano material in various shape. The steps comprises: preparing zinc oxide nano material, preparing SnH4 predecessor material, the produced SnH4 is carried into an air-pocket by nitrogen for emergency, producing SnO2 housing, that is to produce ZnO/SnO2 composite material with kernel-housing structure on the silicon substrate, removing ZnO inner core and getting the SnO2 hollow nano material keeping the ZnO original shape. The ZnO nano material is characterized by the rich shapes, good crystallinity of outer housing and controllable width of the SnO2 hollow material outer wall.
