Abstract

A facile method was developed to synthesize Al(OH)3 nanostructures from Al(OH)3 microagglomerates by dissolution in 9.0 mol·L−1 NaOH at 115°C followed by dilution and aging of the solution at room temperature. The influence of Al(OH)3 nanoseed and surfactants as sodium dodecyl sulfate (SDS), polyethylene glycol 6000 (PEG6000), and cetyltrimethylammonium bromide (CTAB) on the formation of the Al(OH)3 nano-structures was investigated. The experimental results indicated that the Al(OH)3 microspheres composed of nanoparticles were prepared in the blank experiment, while dispersive Al(OH)3 nano-particles with a diameter of 80–100 nm were produced in the presence of Al(OH)3 nano-seed and CTAB.
