Abstract

Anatase TiO₂ nanowires(TNWs) were prepared by hydrothermal technique. The effects of hydrothermal reaction time, hydrothermal reaction temperature and concentration of NaOH on the morphology of TNWs were studied. XRD and SEM were used to characterise the the composition and morphology of TNWs respectively. TNWs and TiO₂(P25) were dispersed in the blended solvent of water and ethanol, receiving uniform and stable slurry. The slurry was coated on surface of the stainless steel substrate to test photoelectric performance. The results show that thin film exhibits the best photovoltaic performance when the doping content of TNWs is 5%(w).
