Spinel ferrites demonstrate extensive applications in different areas, like electrodes for electrochemical devices, gas sensors, catalysts, and magnetic adsorbents environmentally important processes. However, defects the real spinel structure can change many physical chemical properties of ferrites. Although number a crystal lattice is small, their influence on vast majority could be really decisive. This review provides an overview structural characteristics compounds (e.g., CoFe

This study tackles the challenge of applying fine and nano-catalyst particles in Advanced Oxidation Processes (AOPs), primarily due to complexities nanoparticle removal from treated water prevent secondary nano-hazards. We propose an innovative solution: micro-structured ceramic beads (MSCBs, approximately 3 mm diameter) with a unique anisotropic pore structure. For first time, we prepared MSCBs impregnated cobalt oxide (Co/MSCBs) using phase-inversion sintering-assisted process. The Co/MSCBs were investigated for degradation sulfamethoxazole (SMX) peroxymonosulfate (PMS) induced AOPs system under mild reaction conditions. effects operating parameters (e.g., SMX concentration, temperature, catalyst dosage) Co/MSCBs|PMS studied on three different types catalytic beads: 2Co/MSCB0 (beads common isotropic structure), 2Co/MSCB1 radial finger-like microstructures denser outer skin-layer), 2Co/MSCB2 no skin layer). At 20 °C, (59.1 %) demonstrated higher efficiency 40 mg/L comparison (54.9 (49.6 %). Additionally, it is noteworthy that sample 2Co/MSCB2, after being used regenerated, exhibited significantly performance (70.83 % min during 16th run) than fresh one (70.47 120 min). After reactions, can be readily separated bulk solution next run, making them ideal practical applications. Furthermore, radical quenching experiment was conducted, plausible mechanism proposed. research presents new approach fabrication are capable effectively overcoming diffusion limitations encountered both heterogeneous reactions adsorption processes.
