摘要：

A series of vanadotitanium silicates was synthesized by a hydrothermal method. The MEL structure of these synthesized zeolites is clearly evidenced by X-ray diffraction spectroscopy. An advanced study with framework i.r., u,v.-vis, n.m.r., e.p.r., SIMS, and EDS indicates that atoms of both vanadium and titanium are simultaneously and homogeneously incorporated into the framework of the zeolite. In addition, the e.p.r. experiment also shows this zeolite to have redox properties.
