【Abstract】 Heteropolyacids and their salts have been extensively and intensively studied because of their inferesting redox as well as acid-base properties which,in turn,cause their application in heterogeneous and homogeneous catalysis. Reserach effort has been directed towards the entrapment of heteropolyanions in suitable supports,such as activated carbon,zeolite,silica,bauxite,bentonite,montmorillonite,modified clay such as k-10,ion exchange resion,transition metal mixed oxides,pillared layered double hydroxides,conjugated polymer such as polyacetylene,polypyrrole and polyaniline etc.The prepartion,characterization of heteropolyacids doped polyaniline(abbreviated PAN) and their catalytic conversion of isopropanol as the probe reaction are surveyed in this paper.更多还原
