Summary: Oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) are crucial for energy systems like fuel cells and metal-air batteries. Precious metal catalysts, such as Pt and IrO2, have been widely used but their drawbacks necessitate the development of alternative electrochemical catalysts. Transition metal oxides, including Co3O4 and CoFe2O4, show similar ORR and OER activities to precious metal catalysts, making them potential alternatives. In this study, composite catalyst materials were synthesized using hydrothermal synthesis, and they exhibit bi-functional electrochemical catalytic activity for ORR and OER due to their unique nanostructure.

Summary: By doping Te into spinel Co3O4 catalysts, this study successfully reduced the overpotential of the oxygen evolution reaction and increased the efficiency of water splitting. The lattice distortion caused by Te doping resulted in smaller Te-Co3O4 particles with larger surface area for better accessibility of active sites, while the introduction of oxygen vacancies modified the electronic structure and improved the density of active sites. The overall effects contributed to enhanced reaction kinetics and minimized overpotentials in high-performance electrocatalysis.

Summary: The Co3O4 nanoparticle-modified ITO electrodes were successfully prepared using dicarboxylic acid as a self-assembled monolayer. These electrodes showed high electrochemical catalytic activity for oxygen evolution reaction (OER) in acid. The most active assembly exhibited low overpotential and high OER current density, and the electron transfer rate constant was not affected by the carbon chain lengths but enhanced by the larger diameter of Co3O4 nanoparticles. Furthermore, shorter carbon chains and smaller Co3O4 nanoparticles increased the turnover frequency (TOF) of Co sites for OER.

Summary: Co, Ce and Co-Ce nanofibers were synthesized by electrospinning method and applied to gas-solid and solid-solid-gas reactions. Different activity trends were observed in CO oxidation and combustion of diesel soot, with Co-Ce nanofibers showing the highest activity for soot combustion and Co exhibiting the highest activity for CO oxidation. The temperature range for maximum combustion rate was narrow for soot combustion and wider for CO oxidation. The high activity for soot oxidation was attributed to multiple contact points between fibers and soot particles, while the trend observed for CO oxidation was related to the higher redox capacity of Co.
