The adsorption of triethylenediamine (TEDA) on Lewis acid (Al(3+)) sites of the highly dehydroxylated Al(2)O(3) surface has been observed by FT-IR spectroscopy. This was done by monitoring the competitive adsorption of TEDA and CO on the Al(3+) sites. A stoichiometric replacement of Al(3+)-CO species was observed as Al(3+)-TEDA surface species were formed.
通过傅里叶变换红外光谱法观察到三乙烯二胺(TEDA)在高度脱羟基的Al₂O₃表面的路易斯酸(Al³⁺)位点上的吸附。这是通过监测TEDA和CO在Al³⁺位点上的竞争性吸附来实现的。当形成Al³⁺-TEDA表面物种时,观察到Al³⁺-CO物种的化学计量取代。
