Abstract

Detailed analysis of the experimental conditions necessary in order to prepare thermally stable titanium pillared clays are described. pH, temperature and titanium concentration of the suspension play an important role. In the optimal conditions, high surface area Ti PILC (327 m² g⁻¹ at 600 °C) are prepared. In addition, these microporous materials develop strong Lewis acidity evaluated by TPD of ammonia and FT-IR of pyridine.

钛柱粘土的合成与表征制备温度的影响

详细分析了制备热稳定钛柱粘土所需的实验条件。悬浮液的pH、温度和钛的浓度起着重要的作用。在最佳条件下，制备了高比表面积(600℃时为327 m2 g−1)的Ti PILC。此外，用氨的TPD和吡啶的FT-IR评价了这些微孔材料具有较强的刘易斯酸度。
