A novel functionalized porous polythiophene polymer network for Au catalyst deposition

摘要

Highlights•A nitrogen and sulphur rich porous polymer was prepared by oxidative coupling.•The polymer network exhibits moderate BET surface area.•The polymer was an efficient support of Au nanoparticles for reduction reaction with NaBH4.AbstractA porous polymer was synthesized by FeCl3promoted oxidative coupling of 2,4,6-tris(thiophen-2-yl)aniline. Au nanoparticles supported on the polymer network were prepared by in situ reduction method, which exhibit high catalytic activity for catalytic reduction of 4-nitrophenol (4-NP), Congo red (CR) and methylene blue (MB) using NaBH4as reductant. The catalyst can be readily recovered and reused without obvious loss of catalytic activity.
