Facile synthesis of self-assembled mesoporous CuO nanospheres and hollow Cu2O microspheres with excellent adsorption performance†
Abstract
Self-assembled mesoporous CuO nanospheres (CuO NSs) and hollow Cu2O microspheres (Cu2O MSs) were synthesized by a facile ethylene glycol–water solvothermal method without any surfactants. The formation and evolution of copper oxides were investigated by controlling the synthesis conditions. The as-prepared CuxO materials showed an excellent adsorption capability for the quick removal of Acid Orange 7 (AO7) dye in water.
