Abstract: Titanium dioxide (TiO₂) powder was prepared by the solvothermal method. Titanium isopropoxide (C₁₂H₂₈O₄Ti), ammonium hydroxide (NH₄OH) and nitric acid (HNO₃) were used as the starting materials. The mixed solution was diluted to 0.25 M with ethanol (C₂H₅OH) and heated at 100°C-150°C for 3-5 h in a Teflon-lined stainless steel autoclave vessel. TiO₂ powder was characterised with Xray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive spectrometry (EDS). The photocatalytic degradation of phenol over TiO₂ powder under UV light irradiation was studied. The influence of the amount of TiO₂ powder and irradiation time was investigated. The concentration of phenol was measured using UV-Vis spectrometry (UV-Vis). The optimum condition was obtained at 1.0 g.L⁻¹ for the amount of TiO₂ powder and irradiation time was 120 min. It was found that TiO₂ powder prepared by the solvothermal method at 100°C for 3 h has the best performance photocatalytic for degradation of phenol.
