Homogeneous hollow Cu2O octahedral nanostructures have been fabricated by a facile one-pot reduction reaction at room temperature. The microscope analysis revealed that the edges of as-prepared hollow structures were around 200 nm with a wall thickness of about 20 nm. To investigate the influence factors and formation mechanism of the hollow octahedral structure, samples subjected to different reaction conditions were studies. The results showed that the morphology and structures of Cu2O particles were greatly affected by the concentration of pH value of the reaction environment and the reaction time. Ostwald ripening process is proposed to explain the growth mechanism of the hollow octahedral nanostructures.
