Title: Preparation, characterization and applications of HPA-Clay composite as a mild and recyclable heterogeneous catalyst
The pure HPAs (homogeneous liquid phase) as catalysts are advantageous due to their low volatility, low corrosiveness, high acidity, activity and flexibility, the drawback lies in their low surface area (1–10 m2/g) and the problem of separation from the reaction mixture. To overcome the above mentioned problems to be more effective for catalytic reactions, HPAs are usually impregnated on different porous materials. The type of carrier, its textural and structural properties influence the thermal stability and the catalytic activity of Keggin-type heteropolyacids. Clays have been reported to act as catalysts or catalyst supports because of their layer structure, high surface area, pore volume, pore diameter and higher surface acidity. Thus clays can be used as an efficient support for HPAs and it is believed that uniform dispersion of HPAs on porous clay support with high surface area increases the overall acidity and catalytic activity of the composites. High activity of vanadium-containing HPAs and the property of clays as catalyst support prompted us to explore the activity of vanadium substituted TPA supported on clay as a heterogeneous catalyst for the various organic reactions.
