主 题:Graphene oxide Carbon materials Oxidation Low acid Hummers method
摘 要:The production of graphene oxide with less acid is beneficial to reduce the costs and lower the impact on the environment,but it is still a great *** this work,a relatively simple,safe method for synthesizing graphene oxide with much less acid(decrease∼40%)is *** assistance of the heat absorbed from environment and reaction system,the temperature of reaction system of low acid can be well *** interestingly,the graphite can be completely oxidized into graphite oxide by using much less acid,with lowering the production of high-concentration aqueous waste acid(1 mol/L,decrease∼40%).A series of characterizations show that the prepared graphene oxide has similar yield and functional groups compared with that of using the conventional *** work provides a safe and environmentally friendly choice for the large-scale production of graphene oxide and its derivative materials.
