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.
Spark ablation in gas (SAG) technology has the characteristics of being green, fast quenching, fast dynamics and specializes in producing metallic nanoparticles with a clean surface, small size, and abundant defects. In this study, Ag nanoparticles were prepared SAG and loaded on a carbon fiber through nitrogen flow. The effect of the carrier gas flow rate and deposition time on the particle size and the dispersibility of the as-prepared Ag nanoparticles on the carbon fiber by SAG were investigated, and the hydrogen evolution reaction (HER) performances of the samples in acidic media were further studied.
