摘要
本文报道了1:12-磷铜杂多酸(PMo_(12)薄膜修饰碳纤维(CF)微电极的制备及其电化学性质。采用简单,快速的浸渍吸附制备的PMo_(12)薄膜修饰CF电极在酸性介质中具有很高的稳定性和氧化还原活性,电解质溶液的pH值和扫描电位范围对PMo_(12)膜的稳定性和电化学性质产生较大的影响。另一方面,PMo_(12)薄膜修饰CF微电极对酸性水溶液中的PMo_(12)和氯酸根离子(ClO)_3^-)的电催化还原作用也进行了描述。
A monolayer of 1: 12-molybdophosphate acid (PMo_(12)) was modified on a carbon fiber(CF) microelectrode for the first time by simple and rapid dip coating. This modified CF electrode has high stability and redox activity in the acidic media. Cyclic voltammetry was used to study the electrochemical behaviours of PMo_(12) and PMo_(12) filmmodified electrode. It is confirmed that PMo_(12) can be strongly adsorbed on the surface of CF mieroelectrode. The pH of electrolyte solution and the scanning potential range have a strong influence on the electrochemical behaviour and stability of PMo_(12) film modified electrode. On the other hand, the electrocatalytic effect of the PMo_(12) film modified CF microelectrode on PMo_(12) and chlorate anions in aqueous acidic solution is described.
