Title:
TRANSITION METAL-NITROGEN/SULFUR/SELENIUM DOPED POROUS CARBON CATALYST AND NEUTRAL ZINC-AIR BATTERY
Document Type and Number:
WIPO Patent Application WO/2023/246000
Kind Code:
A1
Abstract:
The present invention relates to a transition metal-nitrogen/sulfur/selenium doped porous carbon catalyst and a neutral zinc-air battery. In the neutral zinc-air battery, the transition metal-nitrogen/sulfur/selenium doped porous carbon catalyst is used as an air catalytic electrode, an aqueous solution containing a large-size hydrophobic anion zinc salt is used as an electrolyte, and a zinc material is used as a negative electrode. The transition metal-nitrogen/sulfur/selenium doped porous carbon catalyst comprises a transition metal element, an inorganic doping element, and a porous carbon substrate. Compared with the prior art, the present invention has excellent electronic conductivity and ionic conductivity, and can further reduce the activation energy of ORR/OER reactions, thereby improving the energy density and energy efficiency of neutral zinc-air batteries using the material as an air electrode catalyst.
