【摘要】 通过对介孔氧化硅合成工艺的优化与修正可以用来制备介孔氧化铝分子筛。在合成介孔分子筛的前驱物中掺杂其他金属元素而将其引入骨架或将活性组分负载到介孔分子筛的基体上,可以实现对介孔分子筛表面进行表面修饰与改性,以调变分子筛表面的酸催化性能。本文综述了介孔氧化铝合成、改性研究的历史与现状,及在酸催化过程中的应用。更多还原

【Abstract】 By modifying and optimizing the procedures, which were well-described and understood for the synthesis of mesoporous silica, mesoporous alumina based molecular sieve has been successfully prepared. The regulation of acid catalytic property of molecular sieve can be realized via surface modification of mesoporous molecular sieve by means of introducing doping metals into skeleton or loading active species onto matrix during synthesizing precursor for mesoporous molecular sieve. Various synthetic procedures, modification methods of mesoporous alumina and its application for acid catalysis are reviewed herein.更多还原
