In this study, we prepared a nickel titanate photocatalyst (NTN) using a facile synthesis process with microwave method and applied it for photocatalytic decomposition of gas phase toluene. P25, a commercial photocatalyst, was also employed for the photocatalytic decomposition to compare their photocatalytic performance. NTN exhibited a higher reaction rate constant under visible light irradiation. From XRD patterns and Raman spectra, P25 consisted of anatase and rutile TiO2 structures and NTN existed only in nickel titanate structure. Based on UV-Vis spectra, the bandgaps of P25 and NTN were obtained at 3.2 and 2.20 eV, respectively, implying that NTN would be a visible light-responded photocatalyst. |
