Abstract
Heteropolyacids (HPAs) which are included in mesoporous silica, H3PMo12O40/SiO2 and H4PMo11VO40/SiO2 have been synthesized by a sol–gel technique that involves hydrolysis of ethyl orthosilicate. The effect of incorporation of heteropolyacids species on silica matrix was studied by powder X-ray diffraction (XRD), Fourier transform infrared (FT-IR) and Raman spectroscopy, thermo gravimetric analysis (TGA) and differential thermal analysis (DTA), N2 adsorption–desorption, scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS).
