Synthesis and characterization of a series of novel perovskite-type LaMnO3/Keggin-type polyoxometalate hybrid nanomaterials for fast and selective removal of cationic dyes from aqueous solutions

Keggin-type polyoxometalates (H₃PMo₁₂O₄₀, H₃PW₁₂O₄₀ and H₄SiW₁₂O₄₀) were supported chemically on silicacoated perovskite-type LaMnO₃ nanoparticles for the removal of organic pollutants in water.
