文摘
- •
Ordered mesoporous carbons are oxidized by ammonium persulfate at 60 °C.
- •
Longer oxidation time is favorable for generation of high density of
COOH groups.- •
Dispersion stability of mesoporous carbon is analyzed by optical methods.
- •
Higher transmission intensity is related with more serious sedimentation.
- •
The dispersion of functionalized carbons are much more stable than pure materials.
