Methane adsorption capacity on graphene derived from glucose and ferric chloride

摘要

This study examines the methane adsorption capacity using graphene derived from glucose and ferric chloride (FeCl_3). The graphene was prepared via simple method by dissolution of glucose and FeCl_3 in water, vaporization of water in oven, and calcination process in quartz furnace. Graphene was successfully produced with impregnation ratio of glucose and FeCl_3 at 1:1 and calcination temperature of 650 °C. The prepared graphene subsequently underwent a volumetric adsorption setup, to measure the adsorption capacity of methane (CH4). The highest CH_4 adsorption capacity obtained was 6.37 mmol/g at 3.5 bar and 298 K for 40 minutes. These result shows that the prepared graphene displayed good adsorption characteristic for CH4.
