Abstract:The hexagonal cuprous oxide (Cu2O) hollow structures were prepared by using the air oxidation method. With the aid of oxygen in the air, the hexagonal cuprous oxide (Cu2O) with uniform morphology and uniform size prepared by liquid phase reduction can be hollowed out in situ into a fishbone structure. The morphology, structure and catalytic properties of Cu2O material were characterization by SEM,XRD,TEM,BET and UVVis spectroscopy. The results show that the hexagonal Cu2O was gradually eroded inward along the {100} and {111} planes and the specific surface area of the material increased by 90% after 2 h of airassisted corrosion. The photocatalytic experiment results show that the photocatalytic performance of the hollow Cu2O material is increased by 30%.
