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 Cu_xO materials showed an excellent adsorption capability for the quick removal of Acid Orange 7 (AO7) dye in water.
