Study on Hydrothermal Synthesis and Characterization of Ce-Y/SBA-15 Composite Materials

摘要

Cerium iron was successfully incorporated into an Y/SBA-15 micro-mesoporous molecular sieve via the hydrothermal synthesis method, A series of characterizations were used to characterize the prepared materials such as XRD, N2-adsorption-desorption, SEM-EDS and TEM. The results showed that the prepared composite materials kept the highly ordered mesoporous two-dimension hexagonal structure of SBA-15 and octagonal structure of Y, while the preparation of Ce-Y/SBA-15 composite materials has the advantages of high plentiful cerium iron (2.30 % wt). In the prepared Ce-Y/SBA-15, the frameworks were kept intact, their structures were still kept high ordered and the cerium iron locates inside the pores of Y/SBA-15.
