Hierarchical γ-Al2O3 nanostructures with tunable morphologies, and enhanced adsorption performance towards phenol and CO2 were synthesized for the first time by a facile template-free hydrothermal method using thiourea as precipitating agent.
Three types of resins prepared by carbonyl/amino modification based on CMPS displayed enhanced adsorption capacity towards acid dye Orange G and the resin 135-I-EDA that has two functional groups showed the best adsorption performance.
