通过恒电位方式不添加任何表面活性剂或稳定剂，在ITO表面直接电沉积了枝状的Ag。用SEM、EDS和XRD对其形貌和结构进行了表征，结果显示Ag的形貌为树枝状结构，晶形为立方相的银。电化学分析结果表明，枝状Ag修饰的ITO电极对过氧化氢具有良好的电化学催化还原能力。其作为过氧化氢传感器在较宽（1．96μmol／L 774．2μmol／L）的检测范围，检测限为2μmol／L，响应时间为3 s。计时安培分析发现其对抗坏血酸、L-脯氨酸、L-赖氨酸、L-缬氨酸等干扰物质具有较强的抗干扰能力。

The dendrite Ag was electrodeposited on ITO glasses by a simple potentiostatic method without any surfactant and stabilizing agent.The product was characterized by SEM,EDS and XRD.The results show that the as prepared samples were dendrite structured Ag with cubic phase.The electrochemical measurements show that the dendrite Ag decorated ITO electrode has excellent electrocatalytic reduction ability to hydrogen peroxide.The detection range of H2 O2 on dendrite Ag was about 1.96μmol/L -774.2μmol/L with the detection limit about 2μmol/L and responding time 3s.The chronoamperometry analysis reveals that the H2 O2 sensor has well anti-interference performance toward ascorbic acid, L-proline, L-lysine and L-valine which suggest its potential application in the H2 O2 detection.
