Electrochemical methods were used to prepare CdS ultrafine particle electrode with different particle size. The photoelectrochemical properties of the electrode were investigated by surface photovoltage spectroscopy and photoelectrochemical techniques. The results show that these electrodes have obvious quantum confinement effect. Compared with bulk materials, CdS ultrafine particle electrode shows a high photoelectric response, indicating that the electrode has a unique photoelectric voltage and charge transport mechanism.
