[求助] 计时电量法测量表面积400 μC/cm-2 是什么意思?

计时电量法测量表面积400 μC/cm-2 是什么意思?
如果是金电极的话 400μC/cm2 指的是一平方厘米通过的电量是400,但是没有给出时间啊!
参考文献:The charge consumed during the reduction of
Au oxides has been estimated by integrating the area under the
reductionwave. The surface area ofGNFs on the silicate network
was calculated to be 0.0253 cm2 from the charge consumed
during the reduction of surface oxides using the reported value
of 400 μC/cm2 for a clean Au electrode.
The surface area was
also calculated by chronoamperometry using K3Fe(CN)6 as a
redox probe. The value (0.0249 cm2) calculated from chrono-
amperometry is in close agreement with those obtained by the
voltammetric method.
