AuPt Nanoparticles/ Multi-Walled carbon nanotubes catalyst as high active and stable oxygen reduction catalyst for Al-Air batteries
نویسندگان
چکیده
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 metal loading 10.2 wt% (Au:4.1 wt%, Pt:6.1 wt%) exhibited a superior ORR catalytic activity and competitive durability 20 Pt/C catalyst. When applied as battery, appropriate increasing Au encourage better performance. Au1.68Pt/MWNTs 8.95 little 5.3 Pt content exhibit larger specific capacity (921 mAh g−1) power density (146.8 mW cm−2) well than when it is assembled in battery.

متن کاملChemical vapor deposition synthesis of near-zigzag single-walled carbon nanotubes with stable tube-catalyst interface
Chemical vapor deposition (CVD) growth is regarded as the most promising method for realizing structure-specific single-walled carbon nanotube (SWNT) growth. In the past 20 years, many efforts dedicated to chirality-selective SWNT growth using various strategies have been reported. However, normal CVD growth under constant conditions could not fully optimize the chirality because the randomly f...
متن کاملHigh-precision selective deposition of catalyst for facile localized growth of single-walled carbon nanotubes.
In the liquid-based dip-coating, the hydrophilicity of a Si/SiO(2) substrate is found to be critical for the successful deposition of catalyst and hence the growth of single-walled carbon nanotubes (SWNTs). When the surface is functionalized by a self-assembled monolayer (SAM) and becomes hydrophobic, no catalyst remains and no SWNT grows. This concept can be utilized to localize the growth of ...
