Article Synopsis
- The seawater battery (SWB) shows promise for powering marine electrical devices but faces challenges like low oxygen levels and corrosion from seawater.
- Researchers developed a new strategy to create diatomic catalysts with cobalt (Co) and nickel (Ni) atoms to enhance the battery's efficiency by optimizing oxygen interactions and preventing harmful reactions.
- The CoNi-DAC catalyst demonstrated improved oxygen reduction reaction (ORR) activity, achieving a half-wave potential of 0.79 V and long-lasting performance in seawater, leading to an impressive peak power density of 3.3 W/L.
Effect of Strain Engineering on the Spin State of the Ni-N/C Single-Atom Catalyst and Its Consequence in Electrocatalysis.
ACS Appl Mater Interfaces
September 2024
Strain engineering is an effective strategy to improve the activity of catalysts, especially for flexible carbon-based materials. Nitrogen-coordinated single atomic metals on a carbon skeleton (M-N/C) are of interest in catalytic electroreduction reactions due to their high activity and atomic utilization. However, the effect of strain on the structure-activity relationship between the electrochemical activity and the electronic and geometric structures of Ni-N/C remains unclear.
