Graphene Oxide and Reduced Graphene Oxide Products for Sale

IMPORTANT NOTICE: We are revising our product numbering and several product names soon. For 12 months, both new and old numbers and names will be given to avoid uncertainty.

We produce high quality Hummers method graphene oxide (GO) and reduced graphene oxide (rGO)  in Kg-quantities with excellent reproducibility. We ship the GO-products in the form of aqueous paste and rGO as dry powder. 

Recently we added "fully reduced graphene oxide", "basic GO",  "acid free GO" ,  "dosable rGO-powder" and  "acid free dosable rGO"  to our product portefolio. 

To be launched soon: rGO- and GO-coated glassfibers, GO and rGO decorated with magnetic nanoparticles, GO and rGO decorated with TiO2-nanoparticles and more.

Product 1.2A: Low acid 25 % aqueous GO paste: 25 % GO, 75 % water. This product has been prepared by drying and milling product 1.1 and then re-dispersing in de-ionized water. C/O atomic ratio = 2.5 - 2.6. This GO is a solid acid with about 1.3 mmol total acidity per gram. Total acidity is the sum of acidic functional groups and adsorbed acids (HCl and H₂SO₄). When diluted to 0.1 weight % the suspension has a PH of about 2.9.
