Abstract

The invention discloses a hydrothermal method for preparing copper-nickel-doped nano-zinc oxide photocatalytic materials, which includes the following steps: (1) Prepare raw materials: separately prepare zinc salt water solution, nickel salt water solution and copper salt water solution; (2) prepare basic precursors ; (3) Hydrothermal reaction: place the basic precursor in a reaction kettle, heat, and react; (4) High-temperature calcination: Place the solid obtained by the reaction in step (3) in a muffle furnace for calcination. The present invention uses Zn(NO 3 )·6H 2 O,Ni(NO 3 )·6H 2 O,Cu(SO 4 )·5H 2 O is used as raw material to prepare nano-zinc oxide by hydrothermal method. When the dosage of catalyst is 0.8g / L and irradiated by high-pressure mercury lamp for 90 minutes, the degradation rate of rhodamine B solution (10mg / L) can reach 96.9%.

Description

technical field [0001] The invention relates to the preparation of photocatalytic materials. More specifically, it relates to a process for preparing copper-nickel-doped nano-zinc oxide photocatalytic material by hydrothermal method. Background technique [0002] The development of industry is accompanied by the progress of human science and technology, and at the same time, the problem of environmental pollution is becoming more and more serious. How to control and effectively solve environmental problems is the top priority of the development of human society today. Among environmental problems, water pollution is an important component that is inseparable from human daily life. The rapid development of industrialization has caused the rivers, lakes, and groundwater in our country to be polluted by chemical factors to varying degrees, which has brought great threats and pressures to the lives of our people and the ecological environment. The current water environment is p...
