摘　　要：沸石分子筛孔道和表面化学修饰是对分子筛进行二次合成的重要手段。本文综述了用离子交换法、化学沉积法和分子反应法等手段对各类沸石分子筛孔道和表面进行化学修饰改性的方法,研究结果表明,孔道和表面化学修饰可以精细调变沸石分子筛的孔道和孔口尺寸,钝化非选择性的表面酸性位,固载活性成分,提高分子筛的反应活性和对目标产物的催化选择性,为设计研制新型功能化的沸石分子筛提供有效的途径。Pore and surface chemical modification technology of zeolite is an important way of second synthesis of molecular sieves.Thls paper reviews various pore and surface modification methods including ion exchange, chemical deposition and molecule reaction method, and the results show that pore and surface chemical modification can tailor zeolites＇ pore and pore - opening size, passivate non - selective acid sites and graft active component.Therefore, increasing the activity of zeolite and catalytic selectivity towards aimed products can provide an effective means for designing and researching new functional zeolite.
