【摘要】 石墨烯气凝胶(GAs)具有高比表面积、高机械强度以及高孔隙率等卓越的性能,常应用于催化、吸附、能量储存以及电容等诸多领域。GAs原料易获得,成本低,且反应过程完全绿色,可用于气体性能的吸附研究。本文以氧化石墨烯(GO)和葡萄糖为原料,研究了GO/葡萄糖的不同质量比对有序孔结构的影响和调控机理,并利用比表面积测定仪,SEM,TEM对GAs孔结构进行表征,最终考察调控得到的窄介孔型GAs在气体方面的吸附效率。更多还原

【Abstract】 Graphene aerogels（GAs） with large specific surface area,excellent mechanical performance,and high porosity,are often used in catalysis,adsorption,and energy storage.In addition,the raw materials of Gas are available,low cost,and the reaction process is completely green.In this paper,the effect on the ordered pore structure and regulation mechanism of prepared GAs was studied by different mass ratios of GO/glucose.The textural properties of GAs were characterized via N₂ adsorption/desorption isotherm,SEM,and TEM.And,the gas adsorption efficiency of obtained narrow mesoporous GAs was also investigated.更多还原
