锰基金属有机框架材料催化苯甲醇氧化反应

The Catalytic Properties of Mn-Based Metal-Organic Framework for Benzylalcohol Oxidation

通过二羟基对苯二甲酸和Mn^2+离子的溶剂热反应,制备了一种锰基金属有机框架(Mn-MOF)材料。借助红外(IR)、X-射线粉末衍射(PXRD)、N2吸脱附(BET)等表征手段对所得催化剂的结构及稳定性、微孔形貌进行了表征,考察该催化剂在温和条件下催化氧化苯甲醇制备苯甲醛的催化性能,循环使用10次后转化率可达94%(反应时间6h),有望作为多相催化剂得到应用。

The Mn-based metal-organic framework(Mn-MOF)material was successfully synthesized by reaction of dihydroxyterephthalic acid and Mn 2+ions under solvothermal condition.The synthesized Mn-based MOF was characterized by infrared spectroscopy(IR),powder X-ray diffraction(PXRD),and N 2 absorption-desorption(BET).More importantly,the catalytic measurements show that Mn-MOF was a good catalyst for benzylalcohol oxidation under air conditions and still gives 94%conversion in 6 h after 10 catalytic cycles,implying its good potential application as heterocatalyst.
