LaCo_xMn_1−xO₃ Perovskite Oxide: Its Synthesis and Catalytic Application in Thermal Study of AP

Perovskite oxide due to their structural versatility and compositional flexibility shows potential catalytic performance for redox reactions. So, they can be one of most suitable catalysts to study their effect and mechanism of thermal decomposition of ammonium perchlorate (AP). Here, nano-dimensional perovskite oxide of LaCo_xMn_1−xO₃ (x = 0.2, 0.4, 0.6, 0.8) was synthesized by citric acid sol–gel method and applied as catalyst for thermal decomposition of AP. Structural characterization was studied using various techniques like powder X-ray diffraction (XRD), SEM-EDX, FTIR, UV–VIS spectroscopy, Raman spectroscopy, and Brunauer–Emmett–Teller (BET) analysis. DSC, DTA, TG, and DTG thermal analysis results confirm that LaCo_0.8Mn_0.2O₃ shows best catalyst performance among all. Co metal facilitates the electron transition from CB to VB to create a greater number of reactive sites on the catalyst surface to absorb NH₃ and accelerate the thermal decomposition of AP. So, it can conclude that a higher content of Co metal facilitates the better catalytic performance.
