求助析氫反應(yīng)中,HET速率常數(shù)K0的測(cè)試問題。
|
|
我投了一篇析氫相關(guān)的文章,修改意見讓我測(cè)試一個(gè)HET速率常數(shù)K0,請(qǐng)問這個(gè)測(cè)試的具體測(cè)試方法是什么? 我的測(cè)試方法如下,但是測(cè)試出的結(jié)果峰不明顯,求大神幫我指導(dǎo)一下。 To prepare the testing samples, 4 mg of the sample was dispersed in 1 mL of water/ethanol (3:1) along with 50 μL Nafion (5% w/w in water and 1-propanol) with at least 30 min sonication to form a homogeneous emulsion. Subsequently, 10 μL of the above slurry was dropped onto a glassy carbon electrode (GCE, 3 mm in diameter), and dried naturally. The effective heterogeneous electron transfer (HET) rate constant, keff was determined utilizing a method developed by Nicholson. The specific experiment was realized by a traditional cyclic voltammetry (CV) measurement using 1 mM of potassium hexacyanoferrate (III) (K3Fe(CN)6) aqueous solution, and 0.1 M of potassium chloride (KCl) was used as a supporting electrolyte. The scan range of CV measurements was from -0.6 to 0.6 V, and the scan rate was controlled at 10 mV s-1. |
