基本例句
路易斯碱
The results showed that MgO has a certain strength ofLewis base,and the adsorption of BATE on MgO is monomolecular chemical adsorption.结果表明MgO有一定的路易斯碱强度,与硼酸三甲酯之间的吸附是单分子层化学吸附。
There existed both Lewis acid sites,Mo~) andLewis basesites on the surface of the catalysts.催化剂表面由Lewis碱位及Lewis酸位构成。
FePO 4 and AlPO 4 distribute at intervals, and there existLewis basesites and Lewis acid sites on the catalyst surface.FePO4 和AlPO4 间隔分布在催化剂表面 ;形成Lewis碱位 和Lewis酸位 .
The experimental results pointed out that the three kinds of active sites exist on the surface of the catalysts: Metallic site Cu, Lewis acid sites V~ and Ti~,Lewis basesites bridge O in V-O-Ti and terminal O in V=O.实验结果表明:在Cu/V2O5-TiO2催化剂表面存在金属位Cu、Lewis酸位V5+和Ti4+以及Lewis碱位V-O-Ti的桥氧和V=O的端氧三类活性中心;
