Abstract
Lanthanum-based tri-transition metal-based perovskite structure was synthesized LaMnxCoyFezO3(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 m2/g. N2 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.
以三种不同的组成合成了镧基三过渡金属基钙钛矿结构LaMnxCoyFezO3（x + y + z = 1）。红外光谱分析表明存在M-O键峰。纯立方相的XRD谱图显示其平均晶粒尺寸为11.7 nm。拉曼研究提供了对钙钛矿结构内各种振动模式的见解。煅烧材料的BET表面积为15.5 m2/g。N2吸附曲线表示吸附剂材料的多孔性。通过TGA分析确定了其对高氯酸铵（AP）的催化行为，表明AP的DSC峰、DTG峰和DTA峰分解温度分别降低84℃、81℃和94℃。
期刊介绍：
All new compounds should be satisfactorily identified and proof of their structure given according to generally accepted standards. Structural reports, such as papers exclusively dealing with synthesis and characterization, analytical techniques, or X-ray diffraction studies of metal-organic or organometallic compounds will not be considered. The editors reserve the right to refuse without peer review any manuscript that does not comply with the aims and scope of the journal. Applied Organometallic Chemistry publishes Full Papers, Reviews, Mini Reviews and Communications of scientific research in all areas of organometallic and metal-organic chemistry involving main group metals, transition metals, lanthanides and actinides. All contributions should contain an explicit application of novel compounds, for instance in materials science, nano science, catalysis, chemical vapour deposition, metal-mediated organic synthesis, polymers, bio-organometallics, metallo-therapy, metallo-diagnostics and medicine. Reviews of books covering aspects of the fields of focus are also published.
