This study found that the nature of stabilizing and alkaline agents greatly influence the morphology and photocatalytic activity of NiCr2O4 nanoparticles, with NiCr2O4/Ag nanostructures enhancing the photocatalytic activity for Rhodamine B.
In this study, NiCr2O4 nanoparticles were simply prepared using solutions of nickel nitrate and CrCl3 center dot 6H(2)O and various capping agents in the presence of several alkaline agents. The effects of the presence of different stabilizing and alkaline agents on the size, morphology, and photocatalytic behavior of NiCr2O4 were studied by performing various studies and it was found that the nature of the stabilizing and alkaline agents greatly influence the morphology and photocatalytic activity . Further, the influences of different factors like of the nature of the pollutant, size of the NiCr2O4 particles, and pH of the reaction mixture on the photocatalytic profile of the particles were also evaluated using methylene blue, rhodamine b, and methyl orange as model pollutants. The results indicated the maximum photocatalytic activity in the case of rhodamine B solutions in UV light. It was also noticed that using NiCr2O4/Ag nanostructures increased the photocatalytic activity for rhodamine b from 72 to 83 as opposed to NiCr2O4 nanoparticles.
