Abstract
In this work, the design of nanocomposites LaNiMnO6/K10 (Prv/K10) as a visible-light photocatalyst was studied. Different weight ratios of LaNiMnO6 (5%, 10%, 20%) were loaded into the montmorillonite K10 to create LaNiMnO6/K10 nanocomposites. The samples were characterized by X-ray diffraction, Fourier transforms infrared, Brunauer–Emmett–Teller surface area analysis, scanning electron microscopy, and transmission electron microscopy. Using visible light irradiation, the samples were utilized to decompose crystal violet (CV), as a model of organic pollutant. The effects of initial CV concentration, pH, and catalyst dosage on photocatalytic performance were investigated. The benefits of utilizing K10 as a supporting catalyst are its ease of separation, cheap support and reuse, and the prevention of LaNiMnO6 nanoparticle aggregation. The high catalytic activity appears to be due to the strong absorption of CV and the tiny size of LaNiMnO6 on the K10.
