Abstract
The present invention relates to a nitrate salt-based process for preparing a graphite oxide. The invention nitrate salt-based process employs starting materials comprising a sulfuric acid, an inorganic nitrate salt, an amount of water, a first amount of chlorate salt, and a graphite.
Claims15
A nitrate salt-based process for manufacturing graphite oxide, the process comprising steps of:
- (a) mixing in a reaction vessel a reaction mixture comprising the following starting materials:
- a sulfuric acid, an inorganic nitrate salt, an amount of water, a first amount of a chlorate salt, and a graphite;
- (b) allowing the reaction mixture to react to form graphite oxide;
- and
- (c) separating the graphite oxide from the reaction mixture to give an isolated graphite oxide.
The process as in claim 15, wherein the exfoliated graphite comprises a highly exfoliated graphite, which is characterized as having a Brunauer-Emmett-Teller surface area of from about 200 square meters per gram to about 1500 square meters per gram.
