Catalytic conversion of carbohydrates into 5-hydroxymethylfurfural over cellulose-derived carbonaceous catalyst in ionic liquid

- Cellulose-derived carbonaceous catalyst (CCC) was prepared and characterized.
- CCC was active for the conversion of glucose and other carbohydrates into HMF.
- CCC could be easily recycled and regenerated.
- The mechanism for converting carbohydrates into HMF over CCC was proposed.
