Rechargeable Zn-air batteries are under intensive studies because of their high-energy density, low cost, and safety. However, their wide application is prevented by several remaining technical issues, one of which is the lack of suitable bifunctional cathodic catalysts for oxygen reduction reaction (ORR) during discharging and oxygen evolution reaction (OER) during charging. Due to low material cost...
Nanocomposites of carbon nanotubes (CNTs) with Sb and SnSb 0.5 particles were prepared by chemical reduction of SnCl 2 and SbCl 3 precursors in the presence of CNTs. SEM and TEM imaging showed that the Sb and SnSb 0.5 particles are uniformly deposited on the CNT exterior and in the CNT web. These CNT-metal composites are active anode materials for...
