Abstract

In recent years, bio-inspired synthesis processes have drawn increasing research interest as a new tool for designing next generation advanced functional materials with unparalleled advantages. Bio-inspired process offers unique microstructures which are difficult to engineer through conventional synthesis methodologies. The present study aims to develop a bio-templating process of synthesizing BaBi0.2Co0.35Fe0.45O3-delta (BBCF) perovskite type oxygen separation membrane mimicking the interior of water hyacinth's (Eichhornia crassipes) petioles. In Indian sub-continent water hyacinth is considered as one of the worst aquatic weed whose removal is necessary from natural water reservoir to save aquatic environment. The idea of using such water pollutant to produce engineered microstructure for improving material's functionality is the philosophy behind the present study. The exo-templating of water hyacinth results in interesting microstructure and enhanced the physical properties of BBCF membrane in terms of oxygen permeation flux. The novel, simple method may be extended to produce any multifunctional advanced material with a spectacular microstructure and unique properties. (C) 2016 Elsevier B.V. All rights reserved.
