Preparation and adsorption properties of AlOOH/MWCNTs/Ag nanocomposite
摘要：
AlOOH/MWCNTs/Ag composites have been prepared by oxidation of a mechanical mixture of multi-walled carbon nanotubes (MWCNTs) and electroexplosive bimetallic Al/Ag nanoparticles with water at 60 °C followed by calcination at 300 °C. The composite material obtained consists of nanosheet aluminum structures, carbon nanotubes and silver nanoparticles. Calculation of the composite material promoted the migration of silver nanoparticles to the periphery of the nanosheet structures and the surface of carbon nanotubes, which contributed to a marked increase in the antibacterial activity of the composite material. The specific surface area of the material was 265 m2/g and is determined mainly by nanosheet structures of aluminum oxide. Study of the adsorption properties of the composite material has shown high adsorption towards dyes of different types to an equal extent. The maximum adsorption capacity towards Methylene blue, Eosin and indigo carmine was from 63.1, 75.0 and 82.4 mg/g, respectively. The resulting material can be used as a non-selective adsorbent for purifying water with bacterial contamination.
