diffraction, optical microscopy, SEM, X-ray photoelectron spectroscopy, N2 sorption, thermogravimetry, and IR spectroscopy of adsorbed CO. CO adsorbs on a small number of Cu2O impurities, and particularly on the free CuII coordination sites in the framework. [Cu3(btc)2] is a highly selective Lewis acid catalyst for the isomerization of terpene derivatives, such as the rearrangement of alpha-pinene oxide to
设计了一种优化程序,用于制备微孔金属有机骨架(MOF)[Cu3(btc)2](BTC =苯-1,3,5-三羧酸酯)。通过X射线衍射,光学显微镜,SEM,X射线光电子能谱,N2吸附,热重分析和红外光谱对吸附的CO进行表征。CO吸附在少量Cu2O杂质上,尤其是在游离CuII上框架中的协调站点。[Cu3(btc)2]是用于萜烯衍生物异构化的高选择性路易斯酸催化剂,例如将α-pine烯氧化物重排为樟脑醛和将香茅醛环化为异胡薄荷醇。通过使用2-溴苯乙酮的乙烯缩酮作为测试底物,证明了[Cu3(btc)2]中的活性位是硬路易斯酸。催化剂稳定性,
