Graphite oxide - Wikipedia
Graphite oxide (GO), formerly called graphitic oxide or graphitic acid, is a compound of carbon, oxygen, and hydrogen in variable ratios, obtained by treating graphite with strong oxidizers and acids for resolving of extra metals.
New insights into the structure and reduction of graphite oxide
2009年7月5日 · Graphite oxide is one of the main precursors of graphene-based materials, which are highly promising for various technological applications because of their unusual electronic properties.
Graphite Oxide - an overview | ScienceDirect Topics
Graphite oxide (GO) is a product of using methods, such as Hummer's, to oxidize graphite. This introduces oxygen-containing groups (epoxide and hydroxyl) to the graphite crystal structure. These oxygen groups interact with the water, making the GO hydrophilic.
Graphite Oxide - an overview | ScienceDirect Topics
Graphite oxide is the product of the oxidation of graphite so that the graphitic layers are functionalized with oxygen-containing groups. These groups not only expand the interlayer distance but also make the graphene layers hydrophilic, and as a result, graphite oxide is easy to exfoliate into single layer graphene oxide (GO) in a liquid.
