Synthesis, Characterization and Catalysis Acitivity of the\= MCM\|48 Framework Containing Ti, Co, Cr, Mn, Cu, Mo
【摘要】 合成了掺杂Ti、Zr、Mn、Cu、Mo、Cr、和Co过渡金属离子的中介孔分子筛MCM-48.通过TEM、孔分布测试、XRD、电子能谱、红外吸收及热失重分析对掺杂的MCM-48进行结构表征,并研究了其催化性能.结果表明,掺杂Ti、Cr、Zr的MCM-48具有优良的催化性能
【Abstract】 In this paper, the MCM\|48 framework containing Ti, Co, Zr, Cr, Mn, Cu and Mo was synthesized and characterized by means of HRTEM, pore diameter distribution, XRD, XPS and IR absorption spectra. In addition, we also studied their catalysis behavior for the conversion from eicosanol to eicosanic acid. The experimental results show that the Ti, Cr, Zr doped MCM\|48 pocesses excellent catalysis properties.
