Abstract

Perovskite compounds show great potential in a variety of applications due to their diverse and unique properties and can be modified. Nanomaterial LaCr0.99Fe0.01O3 has been prepared using sol-gel and freeze drying methods. The nanomaterial was then calcined at 700°C for 10 hours and characterized by the analysis techniques of X-Ray Diffraction (XRD), Fourier Transform Infrared (FTIR), Diffuse Reflectance UV-Vis Spectroscopy (DRS UV-Vis), and Transmission Electron Microscopy (TEM). The result of XRD analysis showed that two main crystal phases were formed from the ABO3 perovskite structure, namely LaCrO3 and LaFeO3 which were superimpossed and the crystalline phase size based on the Scherrer method was 23.5 nm. Furthermore, the TEM analysis result shows that there are various forms and hollows. Then, the FTIR spectrum states that there is an interaction between transition metals, and the band gap energy is 2.71 eV.
