Wu, Jiaming published the artcileDesign of graphene oxide by a one-pot synthetic route for catalytic conversion of furfural alcohol to ethyl levulinate, Synthetic Route of 539-88-8, the main research area is ethyl levulinate furfural alc graphene oxide catalytic conversion.
Graphene oxide (GO) has abundant oxygen-containing functionalities such as hydroxyl groups and carboxyl groups with distinct acidities. This feature makes GO a potential solid acid catalyst for the acid-catalyzed reactions such as the production of Et levulinate (EL), a platform chem., from the acid-treatment of furfuryl alc. (FA). The structure and functionalities of GO are closely related to its catalytic performance, and thus it is necessary to establish the relationship between the chem. structure and the catalytic properties of GO. To achieve this aim, in this work, the GO catalysts were designed by a facile one-pot synthetic route with no subsequent modification. By controlling the parameters of oxidation process in preparation, multiple functional groups were immobilized onto graphitic substrate, significantly impacting the catalytic activity of GO in the conversion of FA to EL in an ethanol (EtOH) medium. The results showed that, the oxidation process significantly influenced the distribution of oxygen-containing functionalities on the surface of GO. The amount of the oxygen-containing functionalities can be adjusted by the oxidation parameters such as oxidizing agent equivalent, reaction time and temperature, while the organosulfate can only be remained at a moderate oxidation temperature The existence of the synergistic effect between the oxygen-containing functionalities and the organosulfate functionalities promoted the catalytic activity of GO for the acid-catalyzed conversion of FA to EL. This work provides a new strategy of design and development of functional graphene-based catalysts for the acid-catalyzed reactions, and lays foundation of the practicability of GO in biomass conversion.
