計(jì)時(shí)電量法測(cè)量表面積400 μC/cm-2 是什么意思? 如果是金電極的話 400μC/cm2 指的是一平方厘米通過(guò)的電量是400,但是沒(méi)有給出時(shí)間! 參考文獻(xiàn):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. Zhao, N., Wei, Y., Sun, N.lynnetwwwdagriorglynnet.

這個(gè)是電容的單位啊, 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. 這個(gè)是說(shuō)通過(guò)這方法求電極的活性面積啊,也就是通過(guò)電流對(duì)時(shí)間的1/2次方的斜率來(lái)求得。 |
