摘　　要：In this work,the natural nanozeolite clinoptilolite（Nano CP） was successfully functionalized by propylsulfonic acid and applied as efficient heterogeneous catalyst for the synthesis of quinoxaline derivatives in aqueous media.The nanocatalyst was characterized by various techniques such as CHN,XRD,FT-IR,BET,TGA/DTA,SEM,TEM and TEM-EDS.The results show its applicability as green,reusable and promising catalyst in organic synthesis.It was found that the nanocatalysts could be recycled and reused eight times without significant loss of catalytic activities.In this work,the natural nanozeolite clinoptilolite（Nano CP） was successfully functionalized by propylsulfonic acid and applied as efficient heterogeneous catalyst for the synthesis of quinoxaline derivatives in aqueous media.The nanocatalyst was characterized by various techniques such as CHN,XRD,FT-IR,BET,TGA/DTA,SEM,TEM and TEM-EDS.The results show its applicability as green,reusable and promising catalyst in organic synthesis.It was found that the nanocatalysts could be recycled and reused eight times without significant loss of catalytic activities.
