Embodiment 1

[0020] Put 3g ZnO nanoparticles on 25cm 3 10 g of 10% polyacrylamide was added to the distilled water after a little stirring. After the mixed solution was stirred at 700 rpm for 4 hours, it was dispersed by ultrasonic waves for 1 hour. The ZnO / polyacrylamide nanocomposite can be obtained after drying at 100°C for 4 hours. figure 1 with 2 Electron micrographs of ZnO raw materials and ZnO / polyacrylamide nanocomposites are listed respectively. The ZnO raw material is some agglomerated nanoparticles, and the ZnO / polyacrylamide nanocomposite shows that the ZnO nanoparticles are well dispersed in the polyacrylamide polymer one by one.

[0021] The obtained ZnO / polyacrylamide nanocomposite was treated in 97%N 2 +3%H 2 The C / ZnO nanocomposite was obtained by firing at 700°C for 3 hours in an atmosphere.

[0022] In 10% acetic acid solution 50cm 3 After the C / ZnO nanocomposite was treated to dissolve the ZnO template, the mesoporous carbon material was obtained after washing wi...

Abstract

The invention relates to a preparation method of a mesoporous carbon material, characterized by using ZnO as a template, using organic polymer of dispersible ZnO particles as a carbon source, such as polyacrylamide, and after charing the organic polymer at a high temperature, using organic acid or inorganic acid or alkali to remove the template ZnO to generate mesopores. The mesopores prepared by the invention have same size with the ZnO particles, and a Zn solution after dissolving can be used for synthesizing ZnO nanoparticles repeatedly, thus the purpose of reducing the cost is achieved.

Description

technical field [0001] The invention relates to a preparation method for mesoporous carbon materials. Background technique [0002] Mesoporous refers to pores with a size of 2-50 nm, and mesoporous carbon refers to carbon materials containing such large and small pores. Mesoporous carbon materials are traditional adsorption and separation materials, which can adsorb harmful gases and have selective adsorption and separation capabilities for organic polymers and biopolymers of different sizes. Recently, mesoporous carbons have attracted much attention because of their applications as energy storage materials and energy conversion materials. [0003] Chinese patent CN1821182A disclosed a preparation method of mesoporous carbon materials on August 23, 2006, using sol-gel technology to introduce organic polymers and silicon sources into a surfactant self-assembly reaction system, through organic-organic, Inorganic-inorganic and organic-inorganic competition, polymerization cro...
