he photocatalytic oxidation of the derivatives of p-phenylenediamine (PPDs) was investigated in an UV-illuminated TiO2 dispersion.PPDs were first oxidized to quinonediimine (QDI), QDI deaminized toquinone by the attack of hydroxyl radical. The mechanism and kineticsof the photocatalytic oxidation of PPDs were discussed.

以TIO2作为催化剂,利用波长>330nm的光辐照,研究了N-取代的对苯二胺衍生物(PPDs)的光催化氧化.研究表明,氧分子与光生电子反应生成羟基自由基,羟基自由基氧化PPDs,生成醌二亚胺(QDI),后者在羟基的进攻下脱氨生成苯醌,苯醌继续光解无机化.PPDs光催化氧化近似遵循一级反应动力学.醇类和硫酸根离子可抑制PPDs的光催化氧化.催化剂表面电荷影响电子转移速率,从而控制光催化氧化的反应速率.

Oxygen adsorbed CeO 2, 20% (mol) Ce/Sr and SrCO 3 catalysts for oxidative coupling of methane were studied by EPR and quenching EPR techniques. The formation, adsorption and role of the adsorbed oxygen species were discussed. The results revealed that superoxide ions could be easily formed over ceria and Ce/Sr composite catalysts, while the surface of SrCO 3 was unfavorable for the formation of O - 2 ion.

Oxygen adsorbed CeO 2, 20% (mol) Ce/Sr and SrCO 3 catalysts for oxidative coupling of methane were studied by EPR and quenching EPR techniques. The formation, adsorption and role of the adsorbed oxygen species were discussed. The results revealed that superoxide ions could be easily formed over ceria and Ce/Sr composite catalysts, while the surface of SrCO 3 was unfavorable for the formation of O - 2 ion. It is indicated that O - 2 could be adsorbed in several modes on the surface which showed different stability and oxidizing ability in reaction. O - 2 signals with almost the same intensities were obtained over Ce/Sr composite catalyst using quenching EPR, which implied that O - 2 may not be the selectively active species for the oxidative coupling of methane and might well be transformed to other selective species, like O 2- 2 etc. The oxygen mobility and adsorbing ability for dioxygen of ceria were modulated effectively by SrCO 3 in the composite catalyst, which inhibited the deep oxidation of ceria for the oxidative coupling of methane.

选择CeO2、20%(mol)Ce/Sr及SrCO33种甲烷氧化偶联催化剂,进行了吸附氧的EPR及骤冷EPR研究,对氧物种的形式、吸附方式及在反应中的作用进行了深入讨论.实验发现,氧化铈及复合催化剂很容易吸附氧分子产生O2-超氧离子,而碳酸锶表面不利于O-2的生成.O-2可以不同方式吸附于催化剂表面,不同方式吸附的O-2具有不同的氧化能力和稳定性.不同温度下骤冷可以在复合催化剂上得到几乎相同强度的O-2EPR信号,因此O-2可能不是甲烷的选择活化中心,而是在反应条件下转化成了O2-2或O-选择性物种.复合催化剂中的SrCO3,对CeO2中氧的流动性及产生氧中间体的能力起到了调节作用,抑制了过氧化.
