Abstract

A series of AuPt nanoparticles supported on multi-walled carbon nanotubes (AuxPt/MWNTs) catalysts with ultrafine distribution (d ≈ 3.0 nm) were synthesized for Al-air battery cathode to enhance the oxygen reduction reaction. Among them, Au0.67Pt/MWNTs catalyst with metal loading of 10.2wt.% (Au:4.1wt.%, Pt:6.1wt.%) exhibited a superior ORR catalytic activity and competitive durability to 20wt.% Pt/C catalyst. When applied as Al-air battery, appropriate increasing Au loading encourage better battery performance. Au1.68Pt/MWNTs with 8.95wt.% of Au and as little as 5.3 wt.% Pt content exhibit larger specific capacity (921 mAh g-1) and power density (146.8 mW cm-2) as well as better durability than 20 wt.% Pt/C catalyst when it is assembled as cathode in Al-air battery.
