摘要
采用循环伏安法(CV)研究了2-甲基-1,4-萘醌(MNQ)在不同羟基质子性溶剂中的电化学氧化还原反应。结果表明:MNQ在C2H5OH、CH3COOH中均表现出一对氧化还原峰,在C2H5OH中,其电化学反应是受扩散控制的准可逆过程。而在CH3COOH中,出峰位置均正移,电流响应增强,ΔE值增大,氧化还原峰对称性明显下降。
The electrochemical redox of 2-methyl-1,4-naphthoquinone in C2H5OH and CH3COOH were investigated by cyclic voltammetry.Both one couple of redox peaks is observed.In C2H5OH,it is a quasi reversible process controlled by diffusion.While,in CH3COOH,both Epa and Epc positively shifted.The current response was enhanced.But,ΔE was increased which means the symmetry of the redox peak significantly decreased.
