Abstract

Abstract : We report here a high specific surface area activated carbon loaded with hemin (H-PAC) was synthesized by one-step in situ pyrolysis of paper. As the carrier of hemin, paper- derived activated carbon(PAC) showed high specific surface area (3157 m 2 g −1 ) after optimization. The surface concentration of hemin in the material was effectively increased. Particularly, PAC had a unique interconnected porous structure, which can be used as a continuous conductive framework and provide more active sites. Hemin maintained peroxidase-like activity and showed superior synergistic effect with PAC via pyrolysis, displaying rapid redox characteristics. Under the optimized condition, the composite exhibits high electro–catalytic activities for H2 O2 reduction with a low detection limit of 0.087 μ M, and high selectivity.
