摘要：

Prussian blue (PB) was grown compactly on graphene matrix by electrochemical deposition. The as-prepared PB-graphene modified glassy carbon electrode (PB-graphene/GCE) showed excellent electrocatalytic activity towards both the reduction of hydrogen peroxide and the oxidation of hydrazine, which could be attributed to the remarkable synergistic effect of graphene and PB. The PB-graphene/GCE showed sensitive response to H(2)O(2) with a wide linear range of 10-1440 mu M at 0.0 V. and to hydrazine with a wide linear range of 10-3000 mu M at 0.35 V. The detection limit was 3 mu M and 7 mu M. respectively, and both of them had rapid response within 5s to reach 95% steady state response. The wide linear range, good selectivity and long-time stability of the PB-graphene/GCE make it possible for the practical amperometric detection of hydrogen peroxide and hydrazine.
