| Abstract: | Three solids of composition SiO2, AlPO4 and 20∶80 mol/mol AlPO4/SiO2, respectively, were synthesized. Their textural properties were examined and1H MAS NMR spectroscopy was used to characterize their surface OH groups. The results reveal that the solids are amorphous
and texturally suitable for use as catalysts. |
