To meet the current demands for energy storage and conversion, it is crucial to develop newly designed materials. Porous metal oxides with a high specific surface area and controllable porosity are promising electrode materials for electrochemical energy storage and conversion applications. Furthermore, porous materials offer a unique combination of structural, chemical and physical properties. In this study, porous high-entropy oxides (FeMnCrCoZn)₃O₄ were synthesized through soft chemistry route, employing glycine as a pore-forming agent, followed by calcination at various temperatures (500 °C, 600 °C and 700 °C) for 4h. The obtained samples were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM) techniques. It was observed that the samples were successfully synthesized in porous microsheet morphology and as a single phase in the spinel crystal structure. Additionally, the effect of different calcination temperatures on the pore structure has been investigated.
