Abstract

Lanthanum chromite is a material that plays a large role in the development of fuel cells, catalysts, electronic devices, semiconductors, and magnetics. The application of this compound is determined by the material characteristics. The LaCr1-xVxO3 (where x = 0.01 – 0.03) compound was prepared using a simultaneous method of sol-gel and freeze-drying from salts of chrome, lanthanum, and vanadium in pectin solution. The characterization results using X-ray diffraction, diffuse-reflectance UV-Vis spectrophotometer, and SEM-EDS. X-ray Diffraction analysis showed that the materials formed have the main structure of ABO3 perovskite (such as LaCrO3 and LaVO3) with minor phases of LaVO4 while the band-gap energy of materials due to the addition of vanadium in LaCrO3, it shifts its energy to a lower direction, namely: 2.7; 2.4; 2.6 eV for LaCr1-xVxO3 (where x = 0, 0.01, 0.02, and 0.03) and SEM-EDS micrographs show that the distribution of the crystalline phase is fairly homogeneous, porous and nanorods.
