  1. Rate determining step

    速率控制步驟
  2. 6 ), the process that h20 is adsorbed on the electrode surface and the hydroxyl group is formed to oxidize the co may be the rate - determining step ; in the region iil ( logi > l. 6 ), all of the tafel curves show a curvature until the current densities reach the peak value, indicative of a possible limiting current. the effect of rare earth elements on methanol electro - oxidation has not been reported in literatures

    在低極化區( logi 1 . 3 ) ,甲醇發生脫氫反應並形成反應中間體,其中co成為未被氧化的毒物,此過程成為速率限制步驟;在更高的極化區( 1 . 3 logi 1 . 6 ) , h _ 2o吸附在電極表面並解離生成[ oh ] ,促進了co的氧化,此為此階段速率控制步驟:在第3個極化區( 10gi 1 . 6 ) , tafel曲線發生彎曲,電流密度也最終達到峰值。
  3. The intra - and inter - phase diffusion effects were analyzed. it was pointed out that the rate determining step will change with the temperature. the effective factor was calculated to evaluate the level of the inner diffusion

    對反應中的內、外擴散行為作了分析,指出了速控步驟隨溫度的改變,並計算了衡量內擴散程度的有效因子。
