Abstract

The invention discloses a composite carbon material for seawater desalination and a preparation method of the composite carbon material. The composite carbon material is composed of graphene and activated carbon, wherein the graphene is filled into the surface of the activated carbon. According to the preparation method, the activated carbon and graphene oxide are prepared respectively, and the graphene oxide and the activated carbon are subjected to an ultrasonic reaction and then are subjected to a reduction reaction with glutathione. The composite carbon material is large in specific surface area and clear in pore structure, can provide good ion transmission channels and is simple in preparation process, high in product yield, low in cost, high in resource utilization rate and capable of realizing after-mass production; and meanwhile, the composite carbon material is high in electric capacity, and when the composite carbon material is applied to a deionized capacitor electrode material for seawater desalination, the performance of a deionized capacitor can be improved, and the seawater desalination efficiency is improved.

Description

technical field

[0001] The invention belongs to the field of seawater desalination, in particular to a composite carbon material for seawater desalination and a preparation method thereof. Background technique

[0002] Statistics show that the water resources on the earth are 1.4×1018m 3 , 71% of the Earth's surface is covered by water. However, 98% of these waters are salt water in oceans, inland seas and underground basins, which are not drinkable. Drinkable fresh water only accounts for about 2% of the global total. With the development of the economy and the progress of the society, people's demand for water is increasing, but the shortage of water resources, uneven distribution of time and space, excessive exploitation, unrestrained waste and pollution make fresh water resources become a worldwide issue. Many countries have also begun to look for new water sources. Activated carbon has a high specific surface area, good electrical conductivity, and high electric adso...
