摘      要：Nanobubble is a rising research field,which attracts more and more attentions due to its potential applications in medical science,catalysis,electrochemistry and *** better implement these applications,it is urgent to understand one of the most important mechanisms of nanobubbles,the ***,few attentions have been paid in this aspect because of the methodology *** we successfully used dark-field microscopy to study the evolution process of single nanobubbles generated from formic acid dehydrogenation on single Pd-Ag *** found some of the nanobubbles in this system can exhibit three distinct states representing different sizes,which can transform among each *** transitions are not direct but through some intermediate *** kinetic analysis reveals complicated mechanisms behind the evolution of single *** results acquired from this study can be applicable to nanobubble systems in general and provide insights into the understanding of mechanisms affecting the stability of nanobubbles and their applications.
