When using urea-hydroperoxide as oxygent, just the trimethylphosphine adsorbed on the Lewis acid sites in TS-1 zeolite was oxidized. It further confirmed that the hydroperoxo-titanium species formed by the interaction between the titanium in Lewis acid sites and urea-hydroperoxide are the active oxidation center, and the titanium in the framework as Lewis acid sites enhances the oxidation ability of hydroperoxide. 3.

NO+NH3 temperature-programmed reaction runs over reduced catalyst samples pretreated with various oxidizing species showed that both NO2 and HNO3 were able to reoxidize the V catalyst at much lower temperature than gaseous O2: furthermore, they significantly enhanced the NO + NH3 reactivity below 250 C via the buildup of adsorbed nitrates, which act as a surface pool of oxidizing agents but are decomposed above that temperature.

不+NH3 温度-规划反应奔跑结束减少催化剂样品预先处理与各种不同的氧种表示两者的没有 2 和 HNO3 能够到再氧化 V 催化剂在非常低的温度超过气体的 O2:此外,他们重要地可提高的那不+ NH3 反应度在下面 250?C 经由组织吸附硝酸盐,哪一个行为当做一表面池氧代理人但是被分解上方哪一温度。

Finally, the article discussed the possible mechanism of multi-phase electrochemical degradation of wastewater through the XPS spectrum of the used catalysts surface: In the acid solutions, the electro-generated O_2 may get electrons on the porous graphite cathode and then form H_2O_2, H_2O_2 may diffused to the surface of catalyst and reacted with its active part to produce OH, which in turn can destruct organics. The catalyst functioned as both the catalyst to decompose H_2O_2 and the flocculants to sedimentate the degraded waste.

最后全文结合研究反应后催化剂表面的XPS光电子能谱推断了该体系降解污废水可能的反应机理:在酸性条件下,石墨双阳极产生的O_2被多孔扩散性石墨阴极还原成H_2O_2,并通过扩散传质作用在催化剂的表面活性中心分解为强氧化性中间产物·OH,强氧化性攻击有机物,使其降解为小分子有机物或CO_2和H_2O,催化剂在体系中即起催化作用也起吸附、絮凝作用。
