6.It was found that in the simulated physiological solution , the hydrogen bindings between some amido groups in the mp - 11 molecules are decomposed and the mp - 11 dimers become monomers . it induces the increase in the contents of the a - helical and ( 3 - turn conformation , the decrease in the content of the random coil conformation of mp - 11 as well as the increase in the exposure extent of the heme group . therefore , the reversibility of the electrochemical reaction and the electrocatalytic activity of mp - 11 for h2o2 reduction increase comparing the situation in the aqueous solution
发现在模拟生理条件下, mp - 11分子的多肽链上一些酰氨基的氢键发生了解离,使部分双聚的mp - 11分子变成单体分子, mp - 11分子二级结构中-螺旋和-转角结构的含量增加,无规卷曲结构含量降低,导致了mp - 11分子中血红素的暴露程度变大,因此mp - 11电化学反应的可逆性和对h _ 2o _ 2还原的电催化活性比在水溶液中有所增加。
7.The initial activity of pt / tio2 was higher than that of tio2 because it restrained the recombination of electron and hole with supported pt , however the regenerated ability of the pt / tio2 was lower than that of tio2 . after the regeneration , the activity could come back to some 60 % of the original activity and the reaction activity declined rapidly . the reason might be that after regeneration on the surface of pt / tio2 the incomplete oxidation of h2s to produce s was enhanced
Pt tio _ 2催化剂的初活性比单一的tio _ 2催化剂的初活性高,这是因为担载的贵金属抑制了电子与空穴的复合,但其再生性能比tio _ 2差,再生后活性只能恢复到初活性的约60 ,且反应活性迅速降低,这可能由于在再生后的pt tio _ 2表面上, h _ 2s通过不完全氧化生成s ~ 0的反应增强所致。
