以硼酸三甲酯为探针分子对金属氧化物Al2O3和非金属氧化物SiO2的表面路易斯碱性进行了红外光谱研究.硼酸三甲酯可灵敏地与Al2O3和SiO2的表面路易斯碱中心作用,其红外光谱提供了Al2O3和SiO2的表面路易斯碱性强度的直接信息.

The Lewis base properties of Al_2O_3 and SiO_2 have been studied with an infrared spectroscopic approach by using boric acid trimethyl ester (BATE) as probe molecule.BATE interacts selectively with surface Lewis sites of Al_2O_3 and SiO_2,and its IR spectrum supplies the direct informstion of the stre...
