文摘
- •
Coffee residue has been successfully used to produce sulfonated carbon catalysts (SCAC).
- •
Sulfonation temperature affects SO3H density and O/C ratio of SCAC catalysts.
- •
High catalytic activity and catalyst stability were achieved in SCAC catalysts.
- •
SCAC has unique properties with high surface area and balancing of acid sites.
- •
SCAC could be regenerated to obtain its initial catalytic activity by MeOH washing.
