1H and 31P MAS NMR spectra of solid heteropolyacids (HPA) HmXY12O40 (X = P, Si; Y = W, Mo; m = 3, 4) as well as H3PW12O40 HPA supported on SiO2 were studied. NMR data show the interaction of supported HPA with surface OH groups. Different types of supported species were found to depend on the surface HPA concentration.
