| 摘 要： | 高温下，甲烷在Ｍｏ／ＨＺＳＭ－５分子筛上可直接生成苯［１］．虽然低温下甲烷能被Ｍｏ／ＨＺＳＭ－５催化剂表面的—ＯＨ所活化［２］，但对甲烷在高温下的活化过程知之甚少，然而这却是很重要的．我们采用原位红外光谱技术，研究了甲烷在高温下Ｍｏ／ＨＺＳＭ－５催化...

| Abstract: | Methane activation over Mo/HZSM5 zeolite at high temperature has been studied by FTIR spectroscopy. At high temperature, methane became active and the adsorption bands of methane over Mo/HZSM5 zeolite shift to lower frequencies. Intermediate species was found using differential IR spectroscopic technique reaction times. |
