摘要
Polyaniline (PANI) composite have generated great interest in the catalyst field due to the coordinate properties of their component. Herein, PANI-PMol2 composite mierospheres were successfully fabricated via a facial oxypolymerization with hydrogen peroxide as oxidant and phosphomolybdic acid (PMol2) as dopant. The PANI-PMoI2 microspheres were characterized by SE/vL XRD, FTIR and XPS. The concentration of PMoI2 had a major effect on the diameter of microsphere. The solvent ethanol also played a critical role in the formation of microspheres. The formation mechanism of the PANI-PMol2 microspheres was proposed, Further, the composite microspheres could be directly used as catalyst and displayed a high conversion and selectivity in the epoxidation of cis-cyclooctene with aqueous I-I202 as an oxidant.
