LaMoxV1-xOn Perovskite systems were prepared to be used in natural gas for producing acetic acid. The perovskite systems have been obtained via a sol-gel related method using water as solvelnt. In order to understand the role of the precursor nature and calcinations conditions on the formation of LaMoxV1-xOn an identification using FTIR, XRD, SEM, EDS, TPR, TGA, DTA and Carbon Analyzer was made. The precursor structure is a function of raw material and calcinations conditions. It is show that the nitrate salts of lanthanum, molybdenum and vanadium and calcinations at 750 ºC for 4 hours gave pure LaMoxV1-xOn perovskite with good homogeneity even at nanoscopic scale. These systems are highly efficient catalysts in direct synthesis of acetic acid from natural gas. Studies on the state of these systems after test show the stabilization of perovskite structures. The best-mixed perovskite for the direct synthesis acetic acid from natural gas is LaMo0.7V0.3O4.7 .
