Ethyl levulinate synthesis: Recyclable carbon catalysts for biomass upgrade
Dr. Zhang and Prof. Chen report a simple and effective way for the preparation of inexpensive carbon catalysts from cellulose and metal chlorides. These carbon catalysts exhibit excellent activity in carbohydrate transformation for producing ethyl levulinate. Particularly, FeCl3 modified carbon catalyst shows satisfied activity and stability, and ethyl levulinate yield is significantly improved by around 20% as compared to unmodified carbon catalyst. This work highlights the efficient carbon catalysts from natural resource for biomass upgrade.
