Abstract

Solid acid catalysts, ZrPW (Zirconium (IV) Phosphotungstate) and 12-TPA/ZrO2 [12- Tungstophosphoric acid (12-TPA) supported onto ZrO2] have been synthesized. The catalysts have been characterized for chemical stability, elemental analysis by ICP-AES, TGA, FTIR, SEM, EDX, XRD, surface area (BET) and surface acidity (NH3-TPD). The performance of these materials as solid acid catalysts has been explored by studying ...
