Nanometer rectangular basic copper molybdate and preparation method thereof

Abstract

The invention discloses a preparation method of nanometer rectangular basic copper molybdate. Copper acetate and sodium molybdate as raw materials undergo a one-step hydro-thermal synthesis reaction in a water-glycol mixed solution as a solvent to produce the nanometer rectangular basic copper molybdate. The basic copper molybdate has crystal length of 100-300nm and crystal thickness of 100nm. The preparation method has simple processes and general reaction conditions and can be directly used for industrial large-scale production. The basic copper molybdate nanometer material has stable morphology, high purity and a high degree of crystallization and provides theoretical basis and practical experience for substantial improvement of energy storage and catalysis performances.

Description

【Technical field】 [0001] The invention belongs to the field of inorganic nanometer materials, and relates to a nanoscale cuboid basic copper molybdate and a preparation method thereof. 【Background technique】 [0002] Molybdate micro-nanomaterials are an important class of functional materials, which are widely used in the fields of catalysis, adsorption, electromagnetics, sensors, and energy storage. Among the inorganic molybdate micro-nano materials, the transition metal molybdate has a special crystal structure and catalytic performance due to the existence of empty orbitals. It has received more and more attention. For example, Chinese patents CN201110347395.9 and CN201110347508.5 disclose the preparation of superstructure and radial copper molybdate microspheres (Cu 3 Mo 2 o 9 ), the reaction time of this method is short, but microwave reactors are used, which is not conducive to the industrialized low-cost mass production of products, and its product size is large (5...

AI Technical Summary

Problems solved by technology

At present, there is no extensive report on the synthesis of this natural mineral by artificial means.

Compared with other copper-based molybdates, the morphology of basic copper molybdate is relatively simple, mainly microspheres. For example, Chinese patent CN201510096407.3 discloses a preparation method of micron spherical basic copper molybdate, but The diameter of its product is about 20 μm, and the pH value of the reaction solution needs to be precisely adjusted during the preparation process. Therefore, this method still has room for technical improvement in terms of size control and efficient preparation.
