Description
If you’re formulating a graphene–polymer composite, developing an electrochemical sensor, or engineering an ion-exchange membrane, you need graphene oxide with a reliable carbon-to-oxygen ratio batch after batch. Inconsistent GO is why so many promising lab results never scale.
Our spray-dried graphene oxide powder is manufactured to a tight specification window and QC’d on every lot. You get reproducible performance — so your composite mechanicals, membrane selectivity, or sensor response tracks your process variables, not the material.

Structural Characterization
XRD confirms successful oxidation: strong sharp peak at 2θ ≈ 11° corresponds to the (001) diffraction plane of graphene oxide, indicating well-oxidized, layered GO with interlayer spacing due to oxygen-containing functional groups. A broad hump at 42–44° (100 plane) confirms graphitic in-plane ordering.
XPS: Carbon 67.70%, Oxygen 31.71%, Nitrogen 0.60%. C1s peaks at 284.8 eV (sp² C), 286.6 eV (C–O), 289.8 eV (C=O), 291.9 eV (π–π* shake-up).
