Phosphotungstic acid supported on silica-coated LaCoO3: synthesis, characterization and application as a novel and efficient adsorbent for the removal of organic pollutants

Popis výsledku v původním jazyce

In this work, phosphotungstic acid was supported successfully onto the surface of the silica-coated lanthanum cobaltite and was characterized using different physicochemical techniques including FT-IR, XRD, SEM, TEM, EDX and AFM. Initially, single-phase perovskite-type LaCoO3 nanomaterial was synthesized via the decomposition of La[Co(CN)6].5H2O precursor and then was coated with a SiO2 shell by the Stober method. The as-prepared LaCoO3@SiO2 was used as a support for immobilizing phosphotungstic acid. This novel nanomaterial was used as an adsorbent for the removal of methylene blue and methyl orange organic dyes from aqueous solutions. The results reveal that the newly synthesized hybrid nanomaterial displays enhanced adsorption ability for cationic MB dye compared to bare LaCoO3 nanomaterial, probably due to enhanced electrostatic attraction interactions.
