【摘要】 详细地研究了吸附在热解石墨电极表面的ＳｉＭｏ１２Ｏ４０４－以及Ｄｙ（ＳｉＭｏ１１Ｏ３９）２１３－和吸附在玻碳电极表面的Ｐ２Ｗ１８Ｏ６２６－的电化学行为，结果表明这些杂多化合物修饰电极在酸性条件下均对ＮＯ２－的还原有很好的催化作用，其催化电流与ＮＯ２－的浓度的平方根里线性关系。更多还原

【Abstract】 Electrochemical behavior of Dawson-type P2W18O626- deposited on a glassy carbon electrode, Keggin-type SiMo12O404- and its derivative Dy (SiMo11O39 )213- deposited on a pyrolytic graphite electrode was described. All these modified electrodes displayed catalytic activity for nitrite reduction in acidic solutions and the catalytic current is linear to the square root of nitrite concentration.更多还原
