- •
Treated alloys show excellent low-temperature and high-power output performance.
- •
Duplex hot-alkali treatments promote the surface electrocatalytic activity.
- •
Charge transfer process is the primary control step at extremely low temperature.
- •
Best overall electrochemical properties are got by duplex treatment with NaH2PO2.
