As the problem of environmental pollution has become increasingly aggr avated,the conversion of solar energy catalyzed by semiconductor material has c aused much concern in the field of catalytic and environmental protection.Nano-hematite electrodes with different deposition time were synthesized by electroch emical method more quickly and effectively in this paper.X-ray Diffraction (XRD) and Raman spectroscopy confirmed that the electrode had single phase of hemati te.Morphology information was obtained by Atomic Force Microscope (AFM).The na no-hematite had a particle size of 52.1(±1.48) nm×50.5(±1.49) nm,and the su rface height was concentrated in the range of 70~100 nm,which was consistent with the normal distribution law.Moreover,the UV-Vis Diffuse Reflectance spectr a illustrated the significant absorption of visible light from 350 nm to 600 nm, and the calculating result of band gap was about 2.0~2.1 eV.In photoelectro ch emical experiments,the photocurrent density-time curve and I-V curves indicated that the electrode had great photoelectrocatalysis activity and the reaction pr ocess accorded with the Langmuir-Hinshelwood kinetics model.Furthermore, 10-minute-deposited hematite electrode was used to investigate the activity of photoelectrocatalytic degradation of phenol.The results showed that degradation rate o f phenol reached 62% after 6 h under a constant potential of 0.65 V versus SCE (Saturated Calomel Electrode) and the constant of reaction rate k was 0.16 h^-1 (R₂=0.996) when the first-order kinetics reaction model was fitted. It is thus s hown that the electrochemically deposited nano-hematite possesses satisfying con ductive properties and the capability of degrading phenol and other organic poll utions.
