Problems solved by technology

At present, there are still some transition metals (such as Nb) compared with adjacent metals (such as V, W, Mo, etc.), due to the limitation of the chemical inertness of the metal itself, the alkaline environment and the selectivity of the corresponding soluble metal salts, the development is relatively limited. slow

Embodiment 1

[0044] Bismuth subsalicylate (2.8mmol), NbCl 5(1.4mmol), benzoic acid (4.9mmol), acetonitrile (5mL) and ethanol (5mL) were placed in a 20mL glass bottle, mixed evenly at room temperature, placed in an oven at 80°C at constant temperature, taken out after 7 days, and cooled to room temperature naturally. The solid phase was separated and washed with ethanol to obtain the target product in the form of yellow cubic crystals.

Abstract

The invention belongs to the technical field of preparation of crystal materials, and particularly relates to a preparation method of a BixNby type (such as Bi3Nb18 type and Bi4Nb16 type) polycrystalline crystal. According to the invention, by regulating and controlling synthesis conditions, condensation polymerization reaction is carried out on secondary structure units in a synthesis system to form polycrystalline substances with different sizes and structure types, so that the purpose of constructing metal niobium oxygen clusters with different nanoscale sizes is achieved; through a solvothermal synthesis method, raw materials are subjected to self-assembly reaction, the synthesis steps are simple, the requirement for the purity of the raw materials is low, the raw materials are easy to obtain and low in price, and further purification is not needed.

Description

technical field [0001] The invention belongs to the technical field of crystal materials, and in particular relates to a heterometallic niobium oxycluster compound and its preparation method and application. Background technique [0002] Polyacids, also known as polyoxometalates, can form molecular structures with different nanometer sizes and high core and high symmetry, which can be used to study the relationship between structure and performance. Among transition metals, some polyacids (such as V, W, Mo, etc.) can simply adjust the pH of the synthesis system to obtain a variety of structures, many of which have strong electron and proton transfer / storage capabilities , which is conducive to the study of their internal structure-activity relationship. In fact, multi-acids also show good synergistic effects after being compounded with different functional materials. However, these are based on a good synthetic system. At present, there are still some transition metals (s...
