p.ly-p.anisidine could be easily f.bricated via the oxidative p.lymerization reaction of.p.anisidine using H2O2as the green oxidant. It was unexp.ctedly f.und that zinc dop.ng could signif.cantly imp.ove the adsorp.ion ability of.the material versus heavy metals such as p., Cu,p., Ag and Hg. Results of.nitrogen adsorp.ion–desorp.ion exp.riments demonstrated that Zn dop.ng could enhance the sp.cif.c surf.ce area and mesop.re amount of.the p.ep.red material, which might f.cilitate its absorp.ion to metals. This work not only p.ovides a novel material f.r the treatment of.heavy metal-p.lluted water but also leads to a nice mesop.rous catalyst sup.ort f.r environment p.otection and organic synthesis, i.e. the Zn-dop.d p.ly-p.nisidine can be emp.oyed as the catalyst sup.ort to p.ep.re Cu@p.NI-OMe/Zn or p.@p.NI-OMe/Zn f.r the oxidative degradation reaction of.p.enol or Suzuki–Miyaura coup.ing reactions, resp.ctively. It discloses a new strategy f.r f.bricating the mesop.rous p.lyaniline materials with p.of.und ap.lication p.tential.
