表面活性物質(zhì)覆蓋度(Surface coverage of the redox species )

![]() ![]() ![]() ![]() ![]() ![]() ![]() 本人剛?cè)腴T甲醇燃料電池,有問題請教各位大牛文獻(xiàn)中動力學(xué)研究中有如下公式 The surface coverage of the redox species can be estimated from the following equation Ip = (n2F2/4RT ) vAT 由此公式計(jì)算表面活性物質(zhì)覆蓋度T Where Ip, n, F, R, T, A, v and T are the peak current, the number of transferred electrons, the Faraday constant which equals 96485 C mol-1, the general gas constant which equals 8.314 J K-1 mol-1, the thermodynamic temperature, apparent area of the electrode, the potential scan rate and the surface coverage of the redox species, respective。 本人做鎳催化甲醇電氧化,上述Surface coverage of the redox species(Ni(ii)--Ni(iii)) 計(jì)算出的值跟催化劑的比表面積有關(guān)嗎 ,計(jì)算出的數(shù)值單位是3.1X10-7mol/cm2,請各位大牛多多賜教。它的具體含義是什么,另外有的文獻(xiàn)列出它的值可以換算成比如100層單層活性物質(zhì)。具體含義是什么。謝謝各位. 急急急急急。。。。。 |
