含稀土超强酸催化剂S_2O_8~(2-)/ZrO_2-SiO_2-Sm_2O_3的结构表征

摘要

A novel type of rare earth promoted solid super acid catalyst,S2O82-/ZrO2-SiO2-Sm2O3,was prepared by a special precipitation method,and ammonia persulfate was used as promoter instead of sulfuric acid.The catalysts were characterized by XRD,TG-DTA etc.The XRD patterns of the catalysts belong to amor...
