A sensor based on graphitic mesoporous carbon/ionic liquids composite film for simultaneous determination of hydroquinone and catechol

- Ionic liquid was used as a novel carbon source to synthesize mesoporous carbon.
- A stabilized film of GMC/BMIMPF6 composite can be formed on the electrode surface.
- Two couples of redox peaks for HQ and CC were observed on GMC/BMIMPF6/GC electrode.
