Abstract: Anew type of layered materials pillared by heteropolyanions SiW9M3(M=Mn 2+, Cr 3+, Ti 3+, Fe 3+) were synthesized by means of ion exchange reaction and characterized with elementary analysis, XRD, IRand DTA. The experiments showed that this pillared layered materials had higher catalytic activity for the epoxidation of maleic acid with H2O2.
