摘要
利用水滑石的'记忆效应'将F离子引到铜镍铝水滑石的层板上,并在甲苯的氧化反应中测试其催化性能,运用FTIR、X射线固体粉末衍射技术对其进行了表征,结果表明,引入F离子后的铜镍铝水滑石仍具有良好的层状结构,并表现出了优良的催化活性.在最佳反应条件下,甲苯的转化率最高可达8.4%,苯甲醇的选择性为81.4%.
F- anion was used to modify CuNiA1 hydrotaleite, and then the modified catalyst were tested in the se- lective oxidation of toluene to benzyl alcohol. The structure and the surface properties of catalyst were characterized by FTIR and XRD techniques. The results showed that F-anion modified CuNiA1 hydrotalcite held layer structures, and exhibited high catalytic performance in toluene oxidation. The conversion of toluene reached 8.4% with the se- lectivity of 81.4% to benzyl alcohol.
