Abstract
In this work, the effects of preparation methods such as CE oven, microwave irradiation, and ultrasound on the morphology, particle size and crystallinity of MIL-53(Fe) are firstly investigated. Furthermore, the methods are utilized to prepare Pt NPs@MIL-53(Fe). As a result, well-defined Pt NPs@MIL-53(Fe) prepared by microwave irradiation exhibits uniformed morphology, high crystallinity, and high-disperse Pt NPs, which has been confirmed by FT-IR, TG, N2 adsorption at 77K, TEM and PXRD. Pt NPs@MIL-53(Fe) composite can selectively catalyze the thiophene hydrogenation over nitrobenzene and benzothiophene hydrogenation. The result shows that the sulfur amount can rapidly be reduced to less than 10 ppm and the crystallinity of reacted Pt NPs@MIL-53(Fe) is unchangeable.
