CDO/CO3O4 NANOCOMPOSITE AS AN EFFICIENT ELECTROCATALYST FOR OXYGEN EVOLUTION REACTION IN ALKALINE MEDIA

Electrochemical water splitting is one of the promising way to enhance energy with less outflow. In this regard different electrocatalysts have been reported for Oxygen evolution reaction (OER) to get alternative of noble metal based electrocatalysts. In this work, we have introduced Cadmium-oxide/Cobalt-oxide (CdO/Co3O4) nanocomposite by co-precipitation chemical strategy with impressive OER performance in alkaline medium. Almost 310 mV overpotential value is required to achieve 10 mA/cm2 current density with Tafel slope value of 62 mV/Dec. The as synthesized nanocomposite has stability of 6h as its longer electrochemical performance

Short-Lived Interfaces in Energy Materials

The kinetics of most chemical energy storage/conversion systems depend on the mass transport through matter, which is rate-limited by various kinetic barriers. The distinction of the barriers by static and dynamic interfaces helps in reducing their impact and therefore enhancing the overall kinetics. The concept is introduced along examples of static and dynamic interfaces in hydrogen storage, thermal energy storage in absorptive media, and electrochemical water splitting and CO2 reduction. In addition to the description of analysis methods to probe static and dynamic interfaces, the general strategy as well as concrete examples to overcome them are discussed.
