Abstract

The invention discloses a preparation method of a porous pompon-like zinc oxide material. The method comprises the following steps: zinc salt, acrylic acid and glucose or cane sugar which are used as a raw material undergoes a hydrothermal reaction by using distilled water as a solvent in a teflon autoclave at 160-180 DEG C for 6-12 h, so as to generate a zinc oxide microsphere precursor; and the precursor undergoes heat treatment in a muffle furnace at 500 DEG C for 5 h to obtain the porous pompon-like zinc oxide microspheres with diameter being 1-5 microns. The raw materials such as zinc salt, acrylic acid, glucose or cane sugar, etc. are cheap and easily-available and are low-cost. In addition, a surfactant organic additive is not used. Thus, environmental pollution is reduced. The prepared porous pompon-like zinc oxide material has large specific surface area, and has a broad application prospect in the fields of photocatalytic degradation of dyes, sensors, sewage adsorption, antibacterial materials, energy storage, lithium battery and the like.

Description

technical field [0001] The invention relates to a preparation method of a novel zinc oxide material, in particular to a preparation method of a porous puff-shaped zinc oxide material. Background technique [0002] Zinc oxide is a wide-bandgap direct bandgap II-VI semiconductor material with three crystal structures: tetragonal halite, cubic sphalerite and hexagonal wurtzite. Under normal temperature and pressure, the most common and widely used is the hexagonal wurtzite structure, and the zinc oxide of this structure has good optical, electrical properties and thermal stability. Nano-zinc oxide has the properties of antibacterial, photocatalyst, photoluminescence, conductivity, enhancement, light shielding, wave absorption, energy saving, etc. It can be used as antibacterial agent, ultraviolet shielding agent, photocatalyst, sensor, enhancer, conductive material, energy saving material , piezoelectric materials, etc. Studies have shown that the properties of nanomaterials ...
