本工作采用真空脱气技术对MIL-125(钛)催化剂进行催化氧化脱硫。在300℃真空脱气的MIL-125(Ti)中，准MIL-125(Ti)具有介于原始MIL-125(Ti)和二氧化钛/碳之间的过渡态，还具有独特的结构特征，如较大的孔和丰富的氧空位。其催化活性与氧空位浓度基本一致，分别是纯MIL-125(Ti)和Ti02/C的3.5倍和3.8倍。回收实验证明该催化剂具有良好的稳定性。这项工作为制备用于ODS反应的混合Ti-IV/Ti-III价态钛金属氧化物开辟了一条简单的途径。
In this work, vacuum degas is employed to treat MIL-125(Ti) for catalyzing oxidative desulfurization (ODS). From MIL-125(Ti) by vacuum degassing at 300 degrees C, Quasi-MIL-125(Ti) possesses a transition-state between pristine MIL-125(Ti) and TiO2/Carbon, also has unique structural features, such as larger pores, and abundant oxygen vacancies. Its ODS activity is almost line with the oxygen vacancies concentrations and is approximately 3.5 and 3.8 times higher than that of pristine MIL-125(Ti) and TiO2/Carbon, respectively. And excellent stability of the catalyst was confirmed by recycling experiments. This work opens an easy route for developing mixed Ti-IV/Ti-III valanced Ti-MOFs for ODS reaction.
