| 摘 要： | 利用吸附吡啶的红外光谱对采用水解法和Sol—Gel法制备的钛柱撑蒙脱石和Ti—PLMs表面的酸位进行分析，结果表明：在蒙脱石表面主要存在羟基功能基和L酸位，Ti—PLMs表面除了有很强的L酸位，还出现B酸位。水解法和Sol-Gel法制备的Ti—PLMs相比，后者的L酸位较多,而B酸位较少,认为Ti—PLMs表面的酸位，尤其是B酸位，主要来自于层间产生的TiO2柱子。

| Abstract: | Ti-pillared montmorillonites have been prepared by hydrolysis and Sol-Gel methods. Fourier infrared spectroscopy of pyridine adsorption has been used to determine acid sites on Ti-PLMs. Hydroxy and Bronsted acid sites on the montmorillonites have been identified. There are both Bronsted and Lewis acid sites on the Ti-PLMs. The Ti-PLMs prepared by hydrolysis have more L and less B acid sites than Ti-PLMs prepared by Sol-Gel. It is proposed that the acid sites, especially B acid sites, on the Ti-PLMs originate from the pillars in Ti-PLMs. |
