Abstract

Research shows that the acidic protons can be localized in anhydrous solid acid catalysts by REDOR NMR and density functional theory methods, suggesting that these techniques can be applied to localize protons in heteropolyacid systems. Data indicate that the protons locate at a distance from the Keggin anion central phosphorous.
