Facile synthesis of 3D N-doped porous carbon nanosheets as highly active electrocatalyst toward the reduction of hydrogen peroxide

Abstract

Constructing three-dimensional (3D) conductive framework with high specific surface area and porous structure are indispensable for their applications as electrocatalyst. In this work, we illustrate for the first time that the 3D N-doped porous carbon nanosheets (3D-NS), which was synthesized via a facile one-pot pyrolysis reaction using glucose and melamine as raw materials, can be served as a high performance and green electrocatalyst for the reduction of H2O2. Moreover, a series of 3D-NS samples with controllable content of nitrogen were obtained through adjusting the calcination temperature. From our research, the 3D-NS obtained at 900°C possessed high specific surface area, porous structure, proper dosage of N atoms, suitable degree of graphitization and defects. Furthermore, we also illustrate its application to H2O2 electrochemical sensing in physiological environment. Under optimum conditions, the 3D-NS based sensor displays a wide linear in the range of 0.5–14000 μM and a low detection limit of 0.18 μM (S/N = 3). Therefore, with desirable selectivity, stability and anti-interference performance, the proposed sensor can be feasibly applied to detect H2O2 in human serum samples.
