Green synthesis of oriented xanthan gum-graphene oxide hybrid aerogels for water purification
Copyright © 2017. Published by Elsevier Ltd..
Three-dimensional xanthan gum (XG)/graphene oxide (GO) hybrid aerogels were fabricated by ice crystal templating without using chemical modifiers. The hybrid aerogels were prepared by the stirring of xanthan gum-graphene oxide hybrid solution, followed by freezing at low temperature and finally by freeze-drying. The whole preparation could be completed within 12h without producing any contamination and thus considered a fast, simple, economical, and green method for aerogel fabrication. XG/GO hybrid aerogels possessed different hierarchical pore structures because of various freezing temperatures. A network composed of co-aligned pore channels was obtained at a freezing temperature of -40°C. The as-prepared hybrid aerogels exhibited stability and excellent adsorption capacity for organic dyes and heavy metal ions. Therefore, these aerogels could be used as efficient adsorbents in water purification. This study provided a basis for the cost-effective and large-scale commercial production of high-performance graphene oxide-based aerogels for water purification.
