文摘
- •
Synthesis and characterization of antimony-doped tin oxide aerogels (Sb-doped SnO2).
- •
The best ATO aerogel was decorated with Pt nanoparticles (polyol method).
- •
Pt/Vulcan XC72 was synthesized using the same Pt colloidal suspension.
- •
Two-fold enhancement in specific activity for the ORR on Pt/ATO relative to Pt/C.
- •
Pt/ATO is more resistant to corrosion than Pt/C during accelerated stress testing.
