摘要
基于浸渍法制备得到磷钨酸均匀负载在五乙烯六胺修饰Zr SBA-15的多酸基催化材料;并借助XRD、N2-吸附/脱附等温线、FT-IR、TEM等测试手段对其结构进行了系统表征。以H2O2作为氧化剂,所合成的多酸基复合材料在二苯并噻吩氧化反应中呈现优异催化性能,经6次循环使用后催化性能未有明显降低。
A layer-by-layer stabilization strategy was employed to immobilize active tungstophosphoric acid onto pentaethylenehexamine-preloaded ZrSBA-15. The synthesized materials were characterized by XRD,N2adsorption-desorpton isotherms,FT-IR and TEM,etc. Utilizing hydrogen peroxide as oxidant,the composite exhibited favorable performance toward the deep oxidation desulfurization of dibenzothiophene;and it could be reused at least six runs without discernible decrease in activity.
