preparation example Construction

[0034] A preparation method for covering copper-bismuth nanoparticles on the surface of carbon cloth used for seawater desalination, comprising the following steps:

[0035] (1) Activating the carbon cloth: the carbon cloth is ultrasonicated in deionized water at 50-80°C for 0.5-1 h, and then the carbon cloth is placed in a dilute nitric acid solution. The arrangement direction of the carbon fibers in the carbon cloth is orthogonal distribution, so The thickness of the carbon cloth is 0.294-0.333mm, the volume concentration of the dilute nitric acid is 10%, and the placing time in the dilute nitric acid solution is 15-20min.

[0036] (2) prepare the mixed solution of bismuth salt and citric acid solution, the mass ratio of bismuth salt and citric acid solution is 1-1.5:0.8-1, put the above-mentioned activated carbon cloth into the mixed solution to react, and heat to 75- Reaction at 85°C for 1.8-2h, then heated to 150-170°C for 8-10h, cooled to room temperature, centrifuged, w...

Abstract

The invention relates to the field of environmental protection materials. Aiming at the problems of poor impact resistance and weak light-to-heat conversion ability in the prior art, a preparation method of copper-bismuth nanoparticles on the surface of carbon cloth used for seawater desalination is disclosed. Steps: Put the carbon cloth into deionized water and dilute nitric acid solution for activation; prepare a mixed solution with a mass ratio of bismuth salt and citric acid solution of 1‑1.5:0.8‑1, put the activated carbon cloth into the mixed solution React in solution, heat to 75-85°C for 1.8-2h, then heat to 150-170°C for 8-10h, cool to room temperature, wash and dry in vacuum; put the obtained bismuth-based carbon cloth into 0.5-1mol / L copper salt solution, and then dried, and then calcined under the protection of argon. The invention provides a material with good light absorption and light-to-heat conversion ability and extremely strong, the surface of which can effectively reduce the diffuse reflectance of light, and realize the effective absorption of sunlight in all bands.

Description

technical field [0001] The invention relates to the field of environmental protection materials, in particular to a preparation method for covering the surface of carbon cloth for seawater desalination with copper-bismuth nanoparticles. Background technique [0002] About three-quarters of the earth is covered with water, but most of it is seawater. Freshwater resources closely related to human life are extremely scarce. Seawater desalination is one of the important ways to solve the problem of freshwater resources in the future. Traditional distillation And the reverse osmosis membrane process is the most widely studied and applied seawater desalination technology. Inspired by the natural water cycle process, the use of sunlight to drive water evaporation to obtain clean fresh water has received extensive attention. However, the evaporation of seawater under natural evaporation conditions results in lower utilization of sunlight and slower actual evaporation. The technolog...
