Porous materials with different pore structure were synthesized and modified with Preyssler-type heteropolyacid material by post-synthetic wet-impregnation method. The functionalized materials were thoroughly characterized by different physic-chemical techniques. As reveled by characterization, the structures were well preserved after the modification. All the materials were catalytically active as proved by the catalytic results in dehydration of alcohol to ethylene. On comparison with…
