Characteristics of Polyaniline Cobalt Supported Catalysts for Epoxidation Reactions

The Scientific World Journal, 2014
A study of polyaniline (PANI) doping with various cobalt compounds, that is, cobalt(II) chloride, cobalt(II) acetate, and cobalt(II) salen, is presented. The catalysts were prepared by depositing cobalt compounds onto the polymer surface.
