Poly-p-anisi.i.e could be easily fabricated via the oxidative polymerization reaction of p-anisi.i.e using.H2O2as the g.een oxidant. it was unexpectedly found that zinc doping.could sig.ificantly improve the adsorption ability of the material versus heavy metals such as Pb, Cu,Pd, Ag.and Hg. Results of nitrog.n adsorption–desorption experiments demonstrated that Zn doping.could enhance the specific surface area and mesopore amount of the prepared material, which mig.t facilitate its absorption to metals. This work not only provides a novel material for the treatment of heavy metal-polluted water but also leads to a nice mesoporous catalyst support for environment protection and org.0}c synthesis, i.e. the Zn-doped poly-panisi.i.e can be employed as the catalyst support to prepare Cu@Pani-OMe/Zn or Pd@Pani-OMe/Zn for the oxidative deg.adation reaction of phenol or Suzuki–Miyaura coupling.reactions, respectively. it discloses a new strateg. for fabricating.the mesoporous polyani.i.e materials with profound application potential.
