Flower-like nanometer cobalt hydroxide material and preparation method thereof

Abstract

Disclosed are a flower-like nanometer cobalt hydroxide material and a preparation method thereof. The material is synthesized by the self-assembling method. The preparation method includes that metallic cobalt is reacted with alkali in an oil and water double-phase system at the room temperature, and the flower-like nanometer cobalt hydroxide material is prepared under a guiding effect and a wrapping effect of a soft template with the participation of the soft template. The preparation method is simple to operate and easy to control. The size of a multi-dimensional structure a prepared cobalt hydroxide nanoflower ranges from 300 nanometers to 500 nanometers approximately, the multi-dimensional structure of the nanoflower is self-assembled by cobalt hydroxide plates, and the nanoflower is high in specific surface area and pore volume, and can be applied to fields of battery materials, catalytic materials and the like.

Description

technical field

[0001] The invention belongs to nanometer materials, in particular to a nanometer metal cobalt hydroxide material with a flower shape and its preparation. Background technique

[0002] In recent years, the synthesis of multidimensional structural materials by self-assembly is a hot spot in material synthesis, and morphology control is a key issue in the synthesis of functional materials. Because cobalt hydroxide has unique physical and chemical properties, such as layered structure and good electrochemical redox performance, it has a wide range of applications in the fields of catalysis, electrochemical and gas phase sensors, and has aroused widespread interest. The morphology of cobalt hydroxide has an important influence on its properties and applications. The morphology of cobalt hydroxide has been extensively studied, and one-dimensional structures such as nanosheets, nanowires, nanorods, and nanotubes have been successfully synthesized. However, there ...
