Abstract
With the development of Chinese economic, watershed pollution situation is getting worse and gradually attracts people’s attention. Graphene aerogel (GA) is an ideal material for removing water pollution, due to its high porosity, high specific surface area, and stability. A green and convenient method for GA synthesis was proposed by using graphene oxide dispersion as raw material, triethanolamine as reducing agent, and Blue Moon hand sanitizer as surfactant. The microstructure, hydrophobic and mechanical properties of GA were thoroughly characterized. The adsorption of the prepared aerogel for dichloromethane and ethyl acetate was 240 and 174 times of its own mass, respectively. Moreover, it shows good recirculation adsorption capacity under the 100 compression-adsorption cycles of 50% maximum stress. A paraffin-GA phase change material with good thermal conductivity was also prepared and characterized. This indicates that the prepared GA has a wide range of applications.
期刊介绍：
The Journal of Porous Materials is an interdisciplinary and international periodical devoted to all types of porous materials. Its aim is the rapid publication
of high quality, peer-reviewed papers focused on the synthesis, processing, characterization and property evaluation of all porous materials. The objective is to
establish a unique journal that will serve as a principal means of communication for the growing interdisciplinary field of porous materials.
Porous materials include microporous materials with 50 nm pores.
Examples of microporous materials are natural and synthetic molecular sieves, cationic and anionic clays, pillared clays, tobermorites, pillared Zr and Ti
phosphates, spherosilicates, carbons, porous polymers, xerogels, etc. Mesoporous materials include synthetic molecular sieves, xerogels, aerogels, glasses, glass
ceramics, porous polymers, etc.; while macroporous materials include ceramics, glass ceramics, porous polymers, aerogels, cement, etc. The porous materials
can be crystalline, semicrystalline or noncrystalline, or combinations thereof. They can also be either organic, inorganic, or their composites. The overall
objective of the journal is the establishment of one main forum covering the basic and applied aspects of all porous materials.
