Abstract

Different samples of Ni x K2Mo4O13 have been prepared by mixing appropriate amounts, in solid state, of Ni and K2Mo4O13 (PDF ICDD 27-416) according to the molar ratio Ni/K2Mo4O13 = 0, 0.05, 0.1, 0.2, 0.5, and 1. The prepared samples were characterized using X-ray powder diffraction (XRD), Fourier transform infrared (FT-IR), differential thermal analysis (DTA), nitrogen adsorption apparatus, and UV spectrophotometer. XRD results indicate that the phase composition of the Ni/K2Mo4O13 samples has been significantly changed with the change in molar ratio of Ni/K2Mo4O13. The presence of Ni gave rise to the formation of other new phases identified as K2Mo3O10 (PDF ICDD 37-1467) and α-NiMoO4 (PDF ICDD 32-692). The results of FT-IR and DTA also allowed us to track the formation of the above-mentioned substances. The nitrogen adsorption–desorption isotherms and the pore size distribution reveal that the texture of the prepared samples has also been affected by the nickel content. The photocatalytic behaviors of pure K2Mo4O13 and Ni x K2Mo4O13 were studied by means of monitoring the ability of these materials to enhance the degradation under UV irradiation of the methyl red in liquid media. It was found that the phase composition is the most influential parameter in the photocatalytic behavior of the studied samples.
