摘要

采用酸活化法和铝柱法对美国怀俄明州蒙脱土进行了改性。用这种方法获得的粘土样品，以及起始粘土，用Nafion方法涂在玻碳电极的表面。在缓冲溶液和非缓冲溶液中，研究了这些电极在氧化还原对醌/对苯二酚(Q/QH2)上的活性。粘土改性的类型影响电极的活性和氧化还原反应的机理。

The influence of clay modification on electrochemical behavior of quinhydrone

Montmorillonite originated from Wyoming was modified by acid activation and aluminum pillaring process. The samples of clay obtained in this manner, as well as starting clay, were applied at the surface of a glassy carbon electrode by the means of Nafion. The activity of these electrodes was investigated on the redox couple quinone/hydroquinone (Q/QH2) in buffered and unbuffered solutions. The type of clay modification influenced the activity of the electrodes and the mechanism of the redox reaction.
