Characterisation of supported and unsupported 12-heteropolyacids
Phase transformations of H₄4[SiW₁₂0₄₀]xH₂0 in the temperature range 25 - 900 ⁰C have been investigated and characterised by differential thermal analysis (DTA), thermogravimeteric analysis (TGA), X-ray powder diffraction (XRD), ²⁹Si MAS NMR and FT-IR spectroscopy. Dehydration occurs between 25 - 300...
