Special Issue Information

Dear Colleagues,

Perovskite-based nanomaterials have rapidly become a cornerstone in the advancement of semiconductors and optoelectronics. These materials exhibit remarkable structural, electronic, and optical properties that have driven significant progress in applications such as photovoltaic cells, light-emitting diodes (LEDs), lasers, and photodetectors. The ability to finetune bandgaps, coupled with high absorption coefficients and efficient fabrication methods, positions perovskites as prime candidates for next-generation electronic and optoelectronic devices. This Special Issue seeks to compile pioneering research on the synthesis, characterization, and application of perovskite-based nanomaterials. We welcome contributions that explore innovative material designs, interface engineering strategies, and device architectures that enhance performance and stability. The aim is to showcase the latest advancements in this field and promote interdisciplinary collaboration, accelerating the commercialization of perovskite-based technologies.

This paper presents a comprehensive investigation into the synthesis, morphological characteristics, electrical conductivity, dielectric behavior, and electrocatalytic activity of perovskite-structured iron manganite (FeMnO3), with a specific focus on its performance in the hydrogen evolution reaction (HER). FeMnO3(FMO) nanoparticles (NPs) were synthesized using a sol–gel-type Pechini method and characterized by X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR), and field-emission scanning electron microscopy combined with energy-dispersive X-ray spectroscopy (FESEM-EDS). XRD analysis confirmed the formation of a crystalline structure with cubic symmetry assigned to the Ia-3 space group, with an average crystallite size of 52.47 nm. FESEM images revealed a relatively uniform morphology with an average particle diameter of 55.84 nm. The redox and oxidation states of Fe and Mn can be studied by temperature-programmed oxidation (TPO-O2) in order to understand oxygen uptake and metal oxidation processes occurring within the FMO lattice. The dielectric constant, dielectric loss, electric modulus and electrical conductivity were calculated as a function of frequency and temperature using a Novocontrol Alpha-A broadband dielectric spectrometer (Novocontrol system) coupled with the LCR-800 precision meter. The dielectric data reveal that the FMO has semiconducting behavior with dominant charge- or ionic-relaxation processes. The electrocatalytic activity toward the HER was evaluated using linear sweep voltammetry (LSV), with the working electrode modified by an FMO catalyst ink. The material exhibited significant catalytic activity within the HER potential range, and an increase in the number of cycles led to stabilized current and enhanced hydrogen evolution. These results highlight the stability of FeMnO3 for hydrogen generation. Full article
