Interconnected Porous Material Prepared Via High Internal Phase Emulsion Stabilized by Mixture of Fe3O4 and Tween85

Abstract

PolyHIPE monoliths with open-cell structure were prepared using an oil-in-water Pickering high internal phase emulsion (HIPEs) template. Fe3O4 nanoparticles and Tween 85 were used to stabilize the HIPE. The effects of surfactant concentration, nanoparticle amount and internal phase fraction on the average void and interconnecting pore diameter and interconnectivity degree were investigated. Efficiency of these PolyHIPEs as catalyst for Fenton reaction to decompose methyl orange was tested. The results showed that the PolyHIPE was an excellent and reusable supporter for Fenton reaction.
