Facile Synthesis, Characterization, and Photocatalytic study of La2O3/SnO2 Nanocomposites

In this present work, the La2O3, SnO2, and La2O3/SnO2 nanocomposite (NC) were synthesized by the co-precipitation method at ambient temperature to study the photocatalytic effect. The structural, morphological, and optical characteristics of these prepared samples were analyzed by XRD, FE-SEM, FTIR, Raman, and UV–Visible spectrometer. The photocatalytic activity of the La2O3, SnO2, and La2O3/SnO2 nanocomposite (NC) were studied by observing the decomposition of methylene blue (MB) dye under UV light irradiation at different time intervals. The La2O3/SnO2 nanocomposite removed the methylene blue dye by 92% in 70 min which is highly efficient as compared to the pure La2O3 and SnO2 nanoparticles. Similarly, degradation of La2O3 nanoparticles was found at 80% in 70 min, and tin oxide achieve this at 83% at 70 min for degradation of methylene blue dye. © 2023, The Institution of Engineers (India).
