Abstract

The invention relates to the field of environment-friendly materials, aims to problems that in the prior art, the impact resistance is poor and the light to heat capability is poor, and discloses a method for preparing carbon cloth surface covering copper-bismuth nanoparticles for seawater desalting. The method comprises the following preparation steps: putting carbon cloth into deionized water and a dilute nitric acid solution in sequence, and performing activation; preparing a mixed solution that the mass ratio of bismuth salt to citric acid is (1-1.5):(0.8-1), putting the activated carbon cloth into the mixed solution, performing a reaction, further performing heating to 75-85 DEG C, performing a reaction for 1.8-2 hours, further performing heating to 150-170 DEG C, performing a reaction for 8-10 hours, performing cooling to the room temperature, performing cleaning, and performing vacuum drying; and putting the obtained bismuth-based carbon cloth into a 0.5-1mol / L copper salt solution, performing drying, and further performing calcining in the presence of argon. The invention provides a material with good light absorption, a photo-thermal conversion capability and pole strength, the diffuse reflectance of the surface of the material to light can be effectively reduced, and effective absorption of full-wave bands of sunshine can be achieved.

Description

technical field

[0001] The invention relates to the field of environmental protection materials, in particular to a preparation method for covering copper-bismuth nanoparticles on the surface of carbon cloth used for seawater desalination. Background technique

[0002] About three-quarters of the earth is covered by water, but most of it is seawater. Freshwater resources closely related to human life are extremely scarce. Desalination of seawater 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 researched 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 attracted widespread attention. However, seawater evaporates under natural evaporation conditions, and the utilization rate of sunlight is low, so the actual evaporation is slow. The...
