The removal of gallium from the lattice of MF1-gallosilicates as studied by 71Ga M.A.S-N.M.R spectroscopy

Solid state 71Ga m.a.s.-n.m.r. spectroscopy on MFI-gallosilicates has shown evidence for the removal of tetrahedrally co-ordinated gallium from the zeolite lattice and the concomitant deposition of octahedrally co-ordinated gallium in the pores during steam treatment.
