Published in 2020 at "Hydrometallurgy"

DOI: 10.1016/j.hydromet.2020.105455

Abstract: Abstract Amorphous porous Al2O3 microfiber clusters (AP-Al2O3-MCs) are developed by combining hydrothermal and roasting methods, which are applied to remove F− from the ZnSO4 electrolyte. Comprehensive characterization of AP-Al2O3-MCs is performed using X-ray diffraction (XRD),… read more here.

Published in 2017 at "ACS Sustainable Chemistry & Engineering"

DOI: 10.1021/acssuschemeng.7b00889

Abstract: Porous Al2O3@graphite foams (PAGFs) were directly prepared by a particle-stabilized foaming method, with 40 vol % Al2O3 particles and different proportions of sucrose. The as-prepared PAGFs demonstrate three-dimensional interpenetrating structures and high porosities according to… read more here.
