Abstract

The invention relates to a preparation method of an indium oxide nanorod ordered aggregate, which comprises the following steps of: a, under a stirring condition, adding indium oxide and natrium aceticum in an ethylene glycol water solution to prepare a mixing solution, heating the mixing solution in a closing manner, carrying out thermal reaction to obtain a reaction solution; b, carrying out solid-liquid separation on the reaction solution, washing and drying solids to obtain an indium oxyhydroxide nanorod ordered aggregate; and c, calcining the indium oxyhydroxide nanorod ordered aggregate in air to obtain a hexagonal indium oxide nanorod ordered aggregate or a three-dimensional indium oxide nanorod ordered aggregate. With the ethylene glycol water solution as a reaction medium, and the indium oxyhydroxide nanorod ordered aggregate is prepared in one step by adopting a solvothermal method, thus the preparation method is simple in process; and meanwhile, a structure guide agent or surfactant is not added, thus the cost is lowered.

Description

technical field [0001] The invention relates to a method for preparing an ordered aggregate of indium oxide nanorods, belonging to the technical field of indium oxide nanomaterial preparation. Background technique [0002] Controlling the size and shape of material particles is a research hotspot and difficulty in the field of material synthesis; because the size and shape of materials, especially nanomaterial particles, have an important impact on their properties (Y.Ma, L.Qi, J . Ma and H. Cheng, Cryst. Growth Des., 2004, 4, 351-354.). Chinese patent document CN102134092A (application number 201110039341.6) discloses a method for preparing indium oxide with a new shape. The method uses an inorganic salt solution of indium as an indium source and uses N,N-dimethylformamide (DMF) as a base Source, sodium dodecylsulfonate (SDS) and other anionic surfactants as additives, without adding any hard template, a new type of hollow microspheres with secondary structure and flower-l...
