In situ fabrication of lanthanum-doped nickel oxide nanostructures using sol–gel for the degradation of rhodamine B

Abstract

Various characteristics of pure and La-doped NiO nanostructures were explored with XRD, SEM, EDX, UV-visible, and PL spectroscopy. The 3 wt% La doped NiO sample demonstrates an 84% degradation efficiency with inherent stability showing both effective pollutant removal and sustained performance.
