摘　　要：用电化学石英晶体微天平(EQCM)研究了对苯醌(BQ)对硫酸盐体系镍电沉积的影响。对苯醌通过自身的氧化还原反应影响体系的阴极过程,促进镍的阴极析出,加快镀层的沉积速率。对苯醌对氢析出过程的影响不显著,令阴极电位略有负移。扫描电镜观察显示,对苯醌可以使镀层更平整。The effect of p-benzoquinone(BQ)on electrodeposition of nickel was studied by electrochemical quartz crystal microbalance(EQCM)technique.BQ affects the cathodic process of the system through its oxidation–reduction reaction,promoting the cathodic deposition of nickel and accelerating the deposition rate of nickel coating.BQ has slight effect on the hydrogen evolution process,and makes the cathodic potential shift a little toward negative direction.The result of scanning electron microscopy showed that BQ could make the nickel coating smoother.
