| titleOfInvention | A kind of one kettle way prepares the method for single-layer graphene oxide fast |
| abstract | The invention discloses a kind of method that one kettle way prepares single-layer graphene oxide fast.Graphite and concentrated acid or its nitration mixture are uniformly mixed at 20-50 DEG C and infiltrate 5min-1h, add strong oxidizer and intercalator intercalation, mixed solution is slowly warming up to 30-100 DEG C and Keep agitation 1-10h.Subsequently reaction solution is cooled to 20-37 DEG C, adds a certain amount of concentrated acid or its nitration mixture and slowly add strong oxidizer, at 20-37 DEG C, reacting 0.5-3h, be warming up to below safety temperature 10 DEG C and continue reaction 2-8h, to be oxidized exfoliated graphite layer.After completion of the reaction, products therefrom is slowly poured into the deionization dilution with water of ice, after stable, add hydrogen peroxide, static, the dilute hydrochloric acid of throw out 1mol/L and deionized water are repeatedly cleaned, centrifugation obtains single-layer graphene oxide.Preparation process of the present invention is simply controlled, and time consumption and energy consumption is few, quick by one kettle way, directly graphite is converted into the graphene oxide of individual layer. |
