“…The interest in multivalent mesoporous transition metal oxides originates from their catalytic, electronic, sorption, and magnetic properties, which are superior to those of the respective nonporous material. , Mesoporous structures possess interconnected networks and high surface areas and have shown advantages when used for different catalytic applications, with improved characteristics such as electron transport, dye loading, electrolyte permeation, and oxidative capabilities when compared to those of typical nanostructured catalysts . Our lab has done a considerable amount of work on the synthesis of mesoporous metal oxides in the past few years. − The structural properties of tunable metal oxides, such as surface area, pore volume, and size, and nanocrystalline walls make this oxide class attractive. Expanding these studies to mixed metal oxides has been of interest in the hope that combining the unique advantages of the previously reported inverse micelle synthesis of mesoporous materials with those of mixed metal oxide systems would yield superior catalysts.…”

Nanocrystalline and monomodal pore size mesoporous transition metal oxides have attracted considerable attention because of their interconnected networks and high surface areas. These materials have demonstrated improved characteristics such as electron transport, dye loading, electrolyte permeation, and oxidative capabilities when compared to those of typical nanostructured catalysts when used for different catalytic applications. Of particular interest are ferrites that have demonstrated roles in biomedical and magnetic devices, rechargeable batteries, sensors, catalysis, and water treatment. In addition, microwave hydrothermal synthesis is an attractive method due to its simplicity, rapid synthesis rate, and ease of operation. This paper details the synthesis of mesoporous first-row transition metal ferrites. M 2+ (Mn 2+ , Fe 2+ , Co 2+ , Ni 2+ , Cu 2+ , Zn 2+ ) ferrite synthesis was systematically studied using a Biotage Initiator microwave apparatus, and the effects of reaction time and initial M 2+ concentration on the crystal structure, morphology, composition, and magnetic and catalytic activities were evaluated. Various characterization techniques were utilized to study the synthesis mechanism and characteristics of the materials. These materials were then applied to the electrochemical oxygen evolution reaction, where NiFe 2 O 4 showed high activity vs other ferrites with a low overpotential of 278 mV at 10 mA/cm 2 .
