采用超声波的方法在离子液(1-丁基-3-甲基氯代咪唑盐离子液,[BMIM]Cl)中合成了直径分布在80~150 nm的MoO3纳米棒.采用X射线衍射(XRD)、傅里叶变换红外光谱(FT-IR)、场发射扫描电子显微镜(FESEM)、高分辨透射电子显微镜(HRTEM)和选区电子衍射(SAED)对所合成材料的微观结构和形貌进行了表征.此外,考察了反应时间、加入[BMIM]Cl的量以及其它咪唑基离子液对产物的影响并提出了可能的反应机理.最后对在不同温度煅烧下所得的α-MoO的甲烷催化燃烧活性进行了表征.
The MoO3 nanorods with diameter of 80 ~ 150 nm were synthesized by ultrasonic method in ionic liquid (1-butyl-3-methylchlorimidazolium ionic liquid, [BMIM] Cl) ), Fourier transform infrared spectroscopy (FT-IR), field emission scanning electron microscopy (FESEM), high resolution transmission electron microscopy (HRTEM) and selected area electron diffraction (SAED) In addition, the reaction time, the amount of [BMIM] Cl added and the effect of other imidazolium ionic liquids on the product were investigated and the possible reaction mechanism was proposed.Finally, the catalytic combustion of methane with α-MoO calcined at different temperatures Activity was characterized.
