Figure 6. In situ LC-TEM observations of dynamic behavior of a Pt electrode during electrochemical potential cycling. (A-E) A set of high-resolution TEM images captured during the in situ experiment under different applied potentials. The small white triangles indicate Pt atom dissolution and redeposition[72]. LC-TEM: Liquid cell transmission electron microscopy; TEM: transmission electron microscopy.
