One-Pot Template-Free Synthesis of Mesoporous ZnCo2O4 Microbubbles for Oxygen Evolution Reaction
Spinel ZnCo2O4 is an important multi-functional material with wide applications, such as electrocatalytic oxygen evolution reaction. However, it still remains a challenge to synthesize ZnCo2O4 with complex morphologies by a simple synthetic method. Here, mesoporous ZnCo2O4 microbubbles with hollow structures have been successfully synthesized by a facile one-pot calcination at 400°C in air. The achieved ZnCo2O4 shows a hollow bubble-like microstructure constructed by mesoporous walls, which consist of small primary nanoparticles 9.8 nm in diameter. Although the synthesis route is template/surfactant-free, the pore-size distribution curve shows a sharp peak at 7.6 nm with a very narrow distribution. The specific surface area and pore volume were 68 m2/g and 0.21 cm3/g, respectively. Due to the greatly enhanced mass transfer, the mesoporous ZnCo2O4 microbubbles show attractive electrochemical activity for oxygen evolution reaction.
期刊介绍:
The Journal of Electronic Materials (JEM) reports monthly on the science and technology of electronic materials, while examining new applications for semiconductors, magnetic alloys, dielectrics, nanoscale materials, and photonic materials. The journal welcomes articles on methods for preparing and evaluating the chemical, physical, electronic, and optical properties of these materials. Specific areas of interest are materials for state-of-the-art transistors, nanotechnology, electronic packaging, detectors, emitters, metallization, superconductivity, and energy applications.
Review papers on current topics enable individuals in the field of electronics to keep abreast of activities in areas peripheral to their own. JEM also selects papers from conferences such as the Electronic Materials Conference, the U.S. Workshop on the Physics and Chemistry of II-VI Materials, and the International Conference on Thermoelectrics. It benefits both specialists and non-specialists in the electronic materials field.
A journal of The Minerals, Metals & Materials Society.
