摘　　要：碳布支撑的树枝状PbO_(2)复合电极制备过程简单、成本低、电化学性能良好,为H_(2)O_(2)的检测提供了一种简便可行的途径。文章利用电化学沉积法,通过控制沉积方式和沉积条件,获得了碳布支撑的树枝状PbO_(2)电极(CC-dendritic PbO_(2))和聚集状PbO_(2)电极(CC-agglomerated PbO_(2)),并作为H_(2)O_(2)电化学传感器的电极使用。结果表明:相较于CC-agglomerated PbO_(2),CC-dendritic PbO_(2)对H_(2)O_(2)具有良好的电化学催化活性和选择性,其线性响应范围为5×10^(-6)~1.19×10^(-2)mol/L,检测限为0.781μmol/L(S/N=3);基于这一电极所构建的电化学传感器可以实现实际环境水样中H_(2)O_(2)的检测。With the advantages of simple preparation,low cost and good electrochemical performance,the construction of carbon cloth based dendritic(CC-dendritic)PbO_(2)composite electrode provides a feasible strategy for H_(2)O_(2)detection.This paper,by using electrochemical deposition method and by controlling depositional styles and deposition condition,obtains CC-dendritic PbO_(2)electrode and CC-agglomerated PbO_(2)electrode,and uses them as the electrodes for H_(2)O_(2)electrochemical sensors.The result shows that compared with the CC-agglomerated PbO_(2),CC-dendritic PbO_(2)can indicate a higher electrocatalytic ability and selectivity for H_(2)O_(2).And its linear response range is between 5×10^(-6)-1.19×10^(-2)mol/L and the limit of detection is 0.781μmol/L(S/N=3).H_(2)O_(2)electrochemical sensors based on this electrode can be applicable for the detection of H_(2)O_(2)in various environmental water samples.
