In this study, material with x = 0.01 and x = 0.05 have been successfully synthesized using the sol-gel method. Characterization of the material was carried out by X-ray Diffraction spectroscopy (XRD), Ultraviolet-Visible Spectrophotometry (UV-VIS), and Fourier Transform Infrared Spectroscopy (FTIR). The XRD data of LaFe1-x MgxO3 was confirmed single-phase with orthorhombic structure and Pbnm space groups for all samples. The lattice parameter value increases with increasing Mg content, which is predicted due to the larger ionic radii Mg2+ successfully substituted Fe3+. The crystallite size indicated that samples were nano-scale particles. FTIR spectra confirm that the increased Mg substitution increases the distortion of LaFeO3 lattice, which correlates with XRD results. The UV-Vis characterization aimed to measure the optical bandgap energy. The optical bandgap energy value decreases with increasing Mg doping. Lower optical bandgap value makes a positive impact as promising candidates for photocatalytic applications.
