Graphene oxide enhanced polyacrylamide-alginate aerogels catalysts

[Display omitted] •Graphene oxide enhanced new kind of biomass aerogel catalysts.•Graphene oxide and polyacrylamide enhance the mechanical property of alginate aerogel catalysts by 30 times.•Graphene oxide also significantly increases the catalytic activity. Biomass aerogel is a promising catalyst and has attracted extensive attention. However, most of the biomass aerogels are fragile, which limits their practical application. Herein, we significantly enhance the mechanical property of biomass aerogel catalysts by 30 times through incorporating graphene oxide into polyacrylamide and Cu-cross-linked alginate formed supper-strong double network aerogels. In addition to enhance the mechanical property, the graphene oxide also significantly increases the catalytic activity. Graphene oxide enhancement for biomass aerogel catalyst provides a new method to develop next generation supper catalysts.
