Polyanilines (PANIs) are widely employed materials that are synthesized via the oxidative polymerization of anilines. However, the present synthetic methods always require the use of chemical oxidants and employ HCl/NaOH as the acid-base regulator, resulting in a large amount of waste salt and residual impurities in the material that affect its performance. These drawbacks are unfavorable for industrial applications. A novel method for the preparation of PANIs, i.e. the Se/ZrO2- catalyzed oxidative polymerization of aniline with O2 free of the acid-base regulator is developed. The relatively safe and green features of the method make it more practical for large-scale applications. Researches showed that PANIs prepared by this method could be used as the support to anchor palladium catalyst, and its activity was as good as that of the materials synthesized via traditional methods.
