摘要
介绍了石墨烯的发现过程以及这种材料独特的网络状孔隙结构、较大的比表面积、较高的表面活性等性质,重点介绍了近年来国内外在石墨烯对气体吸附方面的研究进展,从实验和理论两个方面研究了石墨烯对CO2,NO2,NH3等气体的吸附性能,验证了石墨烯对气体具有较好的吸附作用,将石墨烯作为气敏材料用于气体传感器是未来的发展趋势。
The paper briefly introduces the research advances of graphene in recent years. Graphene is the first free-standing two-dimensional atomic crystal which has been found so far. It not only has a very unique pore structure, but has a larger specific surface area and high surface activity. With all these merits, graphene has good adsorption effect, so it is suitable for gas sensors.
