Abstract

Hierarchical core–corona porous γ-Al₂O₃ nanostructures have been synthesized through the reaction of toluene diluted TMA with water by controlling the methane leaching. The obtained γ-Al₂O₃ core–corona nanostructures exhibit high thermal stability and excellent performance for polluted water treatment.
