Journal ArticleDOI
Biomass fly ash geopolymer monoliths for effective methylene blue removal from wastewaters
TL;DR: In this article, fly ash-based monoliths were used as adsorbents for the removal of methylene blue from synthetic wastewaters, and the maximum uptake reported was 15.4 mg/g.
Journal ArticleDOI
Novel porous fly-ash containing geopolymer monoliths for lead adsorption from wastewaters.
TL;DR: These novel geopolymeric monoliths can be used in packed beds that are easily collected when exhausted, which is a major advantage in comparison with the use of powdered adsorbents, and their production encompasses the reuse of biomass fly-ash, mitigating the environmental impact associated with this waste disposal, while decreasing the adsorbent production costs.
Journal ArticleDOI
Porous biomass fly ash-based geopolymers with tailored thermal conductivity
TL;DR: In this paper, porous biomass fly ash-based geopolymers were produced by using hydrogen peroxide as pore forming agent, which can help to mitigate the energy losses inside buildings, while simultaneously reducing the volume of generated wastes, thus contributing towards sustainable construction.
Journal ArticleDOI
Sol gel graphene/TiO2 nanoparticles for the photocatalytic-assisted sensing and abatement of NO2
Andrea Giampiccolo,David M. Tobaldi,Salvatore Leonardi,Billy J. Murdoch,Maria Paula Seabra,Martin P. Ansell,Giovanni Neri,Richard J Ball +7 more
TL;DR: In this paper, a conductometric sensor based on TiO2/graphene prepared using material GTiO2S showed a higher response to NO2 compared to sensors based on pure TiO 2 and TiO 1/Graphene 2 hybrid synthesized through a sol-gel route.
Journal ArticleDOI
Synthesis of porous biomass fly ash-based geopolymer spheres for efficient removal of methylene blue from wastewaters
Rui M. Novais,João Carvalheiras,David M. Tobaldi,Maria Paula Seabra,Robert C. Pullar,João A. Labrincha +5 more
TL;DR: In this article, fly ash (FA)-based adsorbents were used to extract methylene blue from synthetic wastewaters, and the influence of sorption time, dye initial concentration and adsorbent amount on the dye removal efficiency and uptake by the porous spheres was evaluated.
