Abstract

Heteropoly acids (HPAs) have been extensively studied as acid and oxidation catalysts for many reactions and found industrial application in several processes. 1 HPAs are promising solid acids to replace environmentally harmful liquid acid catalysts such as H 2 SO 4 . 1c–f The Keggin type H 3 PW 12 O 40 is more active than conventional solid acids such as SiO 2 –Al 2 O 3 , H 3 PO 4 –SiO 2 , and zeolites. 1c,f Solid acid catalysts are harmless to the environment with ...
