Abstract
Heteropoly acid of Keggin structure tungstovanadogermanic (H5GeW11VO40) has been chemically anchored to the modified SBA-15 surface. The material was characterized by solid-state 29Si MAS NMR, FT-IR spectroscopy, XRD, TG-DTA and N2 adsorption experiments. The preservation of the structure of the HPA and dispersion of the cluster on the support were verified. On the bases of the spectroscopic evidences, HPA clusters were attached firmly to the surface.
