Abstract: The B2O3/MCM-41 material was prepared by the solution-grafting method, using tri-butyl borate as boron source. DTA, XRD, FTIR, XPS and N2 adsorption-desorption isotherms were employed to characterize the synthesized materials. The results show that boron specie separates out and exists as cubic B2O3 after calcining at 400℃. The trigonal BO3 is as the basic coordinated unit in B2O3/MCM-41. The solution-grafting and following calcination have little effect on the structure of MCM-41 host.

Key words: B2O3, MCM-41, solution-grafting
