Problems solved by technology

From the perspective of material morphology, there is no report on coral-like Zn-ZnO composite materials. This structure has a higher specific surface area and more active sites, which is more conducive to further modification and assembly of guest components; From the point of view of the synthesis method of the material, the pre-synthesis of ordered porous ZnO as the precursor by the template method is the prerequisite for obtaining this kind of coral-like material. The shape of the material

Abstract

The invention relates to a coralloidal Zn-ZnO composite material and a preparation method thereof and belongs to the technical field of preparation of nanometer materials. The preparation method comprises the following steps: combining a template method and a hydrothermal method, taking CTAB (Cetyltrimethyl Ammonium Bromide) as a template agent, taking Zn(CH3COO)2 as a zinc source, and synthesizing an ordered porous ZnO powder substrate by adopting the template method; taking the synthesized ordered porous ZnO as a precursor, taking zinc chloride as a mineralizer, and synthesizing the coralloidal Zn-ZnO composite material by adopting the hydrothermal method. The prepared coralloidal Zn-ZnO composite material has large specific surface area, so the gas adsorption ability is excellent. By virtue of observation of a scanning electron microscope, the material has a unique coralloidal structure and good morphology. The novel nanometer structure material has important application prospects.The method disclosed by the invention is simple and feasible, can realize batch production, and has wide application prospects.

Description

technical field [0001] The invention relates to the technical field of nanomaterial preparation, in particular to a coral-like Zn-ZnO composite material and a preparation method thereof. Background technique [0002] According to the pore size of porous materials, porous materials can be divided into three categories, microporous materials, mesoporous materials and macroporous materials, among which mesoporous materials generally refer to pore structure materials with a pore diameter of 2-50nm and a porosity greater than 40%. From the structural point of view, mesoporous nanomaterials can be divided into ordered mesoporous materials and disordered mesoporous nanomaterials. From the perspective of material properties, mesoporous nanomaterials can be divided into organic mesoporous nanomaterials and inorganic mesoporous nanomaterials; from the perspective of chemical composition, mesoporous nanomaterials can be divided into silicon-based mesoporous materials and non-silicon-ba...
