Au nanostructures were potentiostatically electrodeposited (-0.2 V) on Pt electrode (300 um) in 0.5M H2SO4 solution containing 5.0×10-4M HAuCl4 in a classic electrochemical cell several times and for 0.01 s each time. The total charges at the electrode surface were kept at 7.0×10-8C, and then the electrode was rinsed thoroughly with doubly distilled water and allowed to dry in nitrogen at room temperature.
这是从文献上截取的资料，我第一次做电化学，很多问题都不懂，想请问各位高手前辈文献上采用的什么方法电沉积的？在仪器上具体方法是哪一个？他是用辰华的仪器600A做的，我们实验室用的是辰华仪器800系列的，就是不知道该选用什么方法操作？尤其是斜线的部分“several times and for 0.01 s each time”具体是怎么操作控制的？又是怎么精确定量7.0×10-8C的电荷量的？诚挚恳请各位电化学的前辈们给予指导帮助，帮我渡过难关，万般感谢！最后新年将近，祝愿大家新的一年事事顺利！多发高档文章！再次感谢大家！
