Abstract In the present review, the synthesis, characterization, and applications of LaFeO₃ nanoparticles are comprehensively discussed. Various synthesis methods such as sol–gel, co-precipitation, hydrothermal, combustion, and solid-state reactions have been widely employed to prepare LaFeO₃ with controlled morphology, particle size, and crystallinity. The characterization techniques including X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), energy dispersive X-ray spectroscopy (EDX), UV–Vis spectroscopy, and BET surface area analysis are crucial for investigating the structural, optical, morphological, and surface properties of LaFeO₃ nanoparticles. Due to their perovskite structure, excellent thermal stability, narrow band gap, and catalytic activity, LaFeO₃ nanoparticles find promising applications in gas sensing, photocatalysis, solid oxide fuel cells, magnetic devices, and environmental remediation. The review highlights that optimization of synthesis routes and nanostructuring strategies significantly enhance their performance in sensing, catalytic, and energy-related applications, making LaFeO₃ one of the most attractive perovskite materials for advanced functional devices.
Keywords LaFeO₃ nanoparticles, perovskite oxide, gas sensing, photocatalysis, energy applications.
