多金属氧酸盐的电化学性质

利用循环伏安法,研究稀土元素九钨镓杂多酸盐水溶液的电化学性质,结果表明,在0.65~-0.40V的电位区间内,呈现了两对可逆的单电子氧化还原峰,峰电位随着pH值的升高而线性负移,催化活性实验显示,在酸性溶液中该化合物对NaNO2和H2O2的还原反应具有良好的催化作用。

The Electrochemistry Nature of Polymetal Oxyacids Salt

By using circulation Voltammetry,the nature of electrochemistry of rare earth elements-9 tungstic gallium salt brine is studied.The result reveals that,in the electric potential span of 0.65 ~-0.40V,there appear two pairs of peaks of single electron oxidation reduction,the peak electron potential shows linear negative shift with the rise of PH,catalytic activated experiment shows that,in acid fluid,this compound plays a good catalytic role in reduction reaction of NaNO2 and 2O2.
