Abstract:

Carbon catalysis is an attractive metal-free catalytic transformation, and its performance is significantly dependent on the number of accessible active sites. However, owing to the inherent stability of the C-C linkage, only limited active sites at the edge defects of the basal plane can be obtained even after a harsh oxidation treatment. In this study, the concept of interfacial interactions was adopted to propose an efficient strategy to develop highly active carbon catalysts. The alumina/carbon interface formed in situ acted as a cradle for the generation of oxygen-containing functional groups. In the absence of oxidation treatment, the concentration of oxygen-containing functional groups and the specific surface area can reach 1.27 mmol·g-1 and 2340 m2·g-1, respectively, which are significantly higher than those of carbon prepared by traditional hard template methods. This active carbon shows a significant enhancement in catalytic performance in the oxidative coupling of amine to imine, about 22-fold higher than that of a well-known graphite oxide catalyst. Such interfacial interaction strategies are based on sustainable carbon sources and can effectively tune the porous structure of carbon in the micro- and meso-ranges. This conceptual finding offers new opportunities for the development of high-performance carbon-based metal-free catalysts.
