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 μM at 0.0V, and to hydrazine with a wide linear range of 10-3000 μM at 0.35 V. The detection limit was 3 μM and 7 μM, 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.
普鲁士蓝（PB）通过电化学沉积在石墨烯基质上紧密生长。所制备的 PB-石墨烯修饰玻碳电极（PB-石墨烯/GCE）对过氧化氢的还原和联氨的氧化均表现出优异的电催化活性，这归因于石墨烯和 PB 的协同作用。PB-石墨烯/GCE 对 H（2）O（2）具有敏感的响应，在 0.0V 时具有 10-1440 μM 的宽线性范围，对肼具有 10-3000 μM 的宽线性范围。检测限分别为 3 μM 和 7 μM，两者均在 5s 内快速响应，达到 95%的稳态响应。PB-石墨烯/GCE 的宽线性范围、良好的选择性和长时间稳定性使其能够实际安培法检测过氧化氢和肼。
