A new coated type of SnO 2/CdS nanosized composite particles was prepared by wet chemical method. The composition, structure and size of the product were determined by XRD, ICP, TEM and HRTEM. Compared with pure SnO 2 particle, it has stronger absorption in the range of longer wavelength (360～580nm) and shows od photo electrochemical character. The maximum value of IPCE was 40.9%, much greater than that of pure SnO2 electrode, 0.65%. The range photoelectric response has been broadened from 300～400nm to 300～550nm.
