Abstract

The invention discloses a preparation method of a micron-scale flower-like composite metal oxide, relating to a solvent thermosynthesis method of a spinel composite oxide micron flower material. The preparation method comprises the following steps of: with a metal salt as a raw material and glycol as a solvent, adding a surfactant and sodium acetate, and carrying out solvent thermal reaction in a closed container under the condition of 120-220 DEG C to form the micron-scale flower-like composite metal subcarbonate; and with the subcarbonate as a precursor, controlling a temperature rise speed and heating to 300-700 DEG C, and annealing to prepare the corresponding composite metal oxide micron-scale flowers. The preparation method disclosed by the invention has the advantages of simple process, low cost, stable product quality, easiness in control and good process repeatability and can be widely applied to the fields, such as lithium ion batteries, catalysis and the like.

Description

technical field

[0001] The invention relates to a preparation method of a micron-scale flower-shaped composite metal oxide, in particular to a preparation method of a micron-scale flower-shaped composite metal oxide with a spinel structure. The morphology control of spinel oxides is a frontier topic in international nanomaterials research, especially the morphology control of spinel composite oxides has not yet been realized. Background technique

[0002] Among the existing synthesis methods with controllable morphology of spinel oxides, most of them can only control the morphology of single metal oxides. At present, the research on the synthesis of spinel multi-metal oxides at home and abroad mainly focuses on the magnetic iron-containing oxides and bimetallic types. L.S.Zhong et al. reported in "Advanced Materials" 2006, Volume 18, page 2426 that the self-assembled three-dimensional flower-like nanostructure of iron oxide has a good effect in sewage treatment.
