Porous copper oxide (CuO) hollow microspheres were fabricated via a one-step method.The products were characterized by SEM,XRD and FTIR.The carbon source,hydrothermal temperature and time and the concentration of CuSO4 play crucial roles in controlling the morphology of the title material.A formation mechanism was proposed based on the characterization results.The BET specific surface area of the hollow spheres is 409 m2·g-1,the average pore size is 3.15 nm,and the total pore volume is 0.256 cm3·g-1.The material exhibits a quantum size effect in UV spectrum and higher photocatalytic activity for degradation of rhodamine B (RhB) aqueous solution.
