AbstractIn this paper, the K2NiF4 system, La2NiO4+δ, has been analysed for potential photocatalytic activity for destruction of organic pollutants under low intensity UV light, with methyl orange used as model pollutants. The La2NiO4+δ, was shown to have promising photocatalytic activity. In addition, there was also evidence for catalytic decomposition of methyl orange in the dark, most likely due to a redox process, although further work is required to confirm this. The results show that the nanoLa2NiO4 samples prepared by sol-gel method have better photocatalytic activity than La2NiO4 prepared by solid state method since the sol-gel method produces a smaller particles sizes comparing to the solid state method. X-ray diffraction (XRD), thermogravimetric analyses (TGA), and The Brunauer–Emmett–Teller (BET) were used for surface characterizations.
