Fabrication of Highly Ordered Carbon Networks as Catalyst Supports for Aerobic Oxidation of Glucose

Article Preview

Abstract:

Highly ordered macro- and meso- porous carbon materials were prepared in a facile nanocasting approach using colloidal crystals silica and SBA-15 as starting template, respectively. The synthesized macroporous carbon templated from colloidal silica shows a honeycomb-like morphology and three-dimensionally interconnected networks of macrospores of about 400 nm in diameter. The resulting mesoporous carbon derived from SBA-15 templates exhibits high specific area (1206m2/g), large pore volume (1.097cc/g) and uniform pore size distribution (3.64 nm). These carbon materials were employed to aerobic oxidation of glucose as support of Au NPs catalyst. 2wt% Au NPs/mesoporous carbon shows high catalytic activity due to highly dispersion of Au NPs resulting from the confinement effects of mesoporous carbon.
