Hydrolysis of cellulose as an important part of biomass conversion plays an essential role in realizing the utilization of biomass energy.Solid acid catalyst has attracted more attention due to its low cost and easy post separation with reducing sugars.Among various types of solid acid catalyst, sulfonated carbon catalyst has excellent catalytic activity with SO3H group serving as the main active catalytic site.In this work, advanced carbon acidic catalytic with -Cl binding sites has been designed and synthesized by using solution plasma technology and gas-liquid interfacial plasma.First, the -Cl doped carbon is effectively prepared by using a one-step SP process at room temperature.Then, green sulfonation of the Cl-doped carbon was performed by GLIP process in dilute sulfuric acid.In summary, the stable catalytic performance of cellulose hydrolysis showed that there is no obvious leaching of functional groups even after 3rd recycle for sulfonated C-Cl. Moreover, the total conversion rate and glucose selectivity by sulfonated C-Cl is higher than sulfonated C, it implies the Cl groups serve as the bonding site well that greatly promote the hydrolysis process of cellulose. |
