Abstract
Current research aims to improve the characteristics of lithium manganese oxide (LiMn2O4), a highly prospective for waste water treatment applications, by incorporating gadolinium (Gd-0.25 %) into the manganese position. This integration, achieved via conventional ball milling, aims to improve the structural, morphological, and electrical characteristics of Li4Mn5O12. A range of analytical methods, such as X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), and impedance testing, were utilized to evaluate the influence of Gd-0.25 % on Li4Mn5O12. The results indicate that the inclusion of Gd at the manganese sites enhances the thermal conductivity of Li4Mn5O12 (Li4Mn4.75Gd0.25O12), leading to improved conductivity compared to undoped Li4Mn5O12. Additionally, the enhanced material exhibits promising potential as an efficient photocatalyst, demonstrated by its degradation of methylene blue (MB) dye.
