Tri‐Transition Metal‐Substituted Lanthanum‐Based Perovskite Formulation for Catalytic Application in AP

ABSTRACT Lanthanum‐based tri‐transition metal‐based perovskite structure was synthesized LaMn x Co y Fe z O 3 ( x + y + z = 1) in three different compositions. IR spectroscopy shows the existence of M‐O bond peak. The XRD patterns of pure cubic phase show an average crystalline size of 11.7 nm. Raman study provides insights into the various modes of vibration within the perovskite structure. BET surface area of the calcined material was 15.5 m 2 /g. N 2 adsorption curve signifies the porous nature of the adsorbent material. Its catalytic behavior towards ammonium perchlorate (AP) was established by TGA analysis, which shows 84 °C, 81 °C, and 94 °C decrease in the DSC peak, DTG peak, and DTA peak decomposition temperature of AP. Artificial neural networks were applied to forecast the TG curves and activation energy values.
