The electrochemical surface area (ESA) of Pt/Vulcan XC-72 electrode decreases by 49.8% after ADT, while only 26.1% for Pt/CNT, which means that PT/CNT is more stable than Pt/Vulcan XC-72 under electrochemical operation.

• 将Pt/CNT和Pt/Vulcan XC-72置于100~175℃干燥的空气中,192 h的时间范围内,两者的质量和化学比表面积均无明显变化。 Pt/CNT和Pt/Vulcan XC-72颗粒在该温度范围内的干燥空气中较为稳定。
