Abstract

The invention relates to a method for preparing a Cu2O solid microsphere. The method comprises the following six steps. According to the basic mode, the microsphere is prepared by employing a water bath method, the addition amount of hydroxylamine hydrochloride (NH2OH.HCl) and lauryl sodium sulfate (SDS) in the preparation process, and the Cu2O solid microsphere with the uniform size and different surface features is obtained. The photocatalytic performance is influenced by the surface features of the Cu2O solid microsphere, and the photocatalytic performance can be obviously improved through the nano-pore structure on the surface. The SDS surfactant can be uniformly arranged into spherical micelles in a unified mode in the water bath process, the SDS surfactant serves as a flexible template in the whole Cu2O nucleation process, and the formation of the Cu2O microsphere with the solid structure is regulated. The Cu2O microsphere has high application value and wide application prospect in the technical fields of materials, environment and new energy.

Description

technical field [0001] The present invention relates to a Cu 2 O Preparation method of solid microspheres. It can make Cu 2 O solid microspheres have a surface nanoporous structure, which can significantly improve the Cu 2 The photocatalytic performance of O microspheres belongs to the technical fields of materials, environment and new energy. Background technique [0002] With the rapid development of human society and economy in the 20th century, a series of major problems such as environmental pollution, energy shortage, and ecological destruction have also emerged. The development and research of photocatalytic materials is gradually attracting people's attention in the field of energy conversion and environmental protection, and its application market is gradually forming. Cu 2 O is recognized by many experts in recent years and is expected to become the successor to TiO 2 The potential new material that can be used later is a green and environmentally friendly ph...
