Abstract

The invention discloses an In with a core-shell structure 2 o 3 The synthesis method of the dodecahedron uses In-based MOF as the precursor, and the dodecahedral In-based MOF with a small size and uniform shape is used as the precursor. Selecting the appropriate calcination temperature, calcination time and calcination atmosphere can form a core-shell Structure of indium oxide dodecahedron.

Description

technical field [0001] The present invention relates to the use of an In with a core-shell structure 2 o 3 The synthesis method of the dodecahedron belongs to the preparation technology of materials. Background technique [0002] The morphology of micro-nano materials is an important factor affecting their properties. How to control the synthesis of metal oxide micro-nanocrystals with specific morphology has become a hot topic in current research. Metal-organic frameworks (MOFs) are a new class of organic-inorganic hybrid materials formed by the self-assembly of inorganic metal ions and organic ligands. Compared with traditional inorganic porous materials, it has higher specific surface area, porosity and regular channels, and its structure is easy to adjust. Using MOFs as precursors to prepare metal oxides has many advantages, and the calcined materials can maintain the framework and porous structure of MOFs precursors. The present invention uses dodecahedral In-based ...
