研究目的
Investigating the unusual volume shrinkage phenomenon during the potassiation of CuO nanowires and understanding the underlying mechanisms.
研究成果
The volume shrinkage during the potassiation of CuO nanowires is caused by a peculiar 'oxygen pump' and electrochemically driven Kirkendall effect, revealing a new ion migration mechanism during electrochemical reactions.
研究不足
The study is limited to the observation of volume shrinkage in CuO nanowires during potassiation under specific experimental conditions. The generalizability of the findings to other materials or conditions is not explored.
