Well‐defined Cu 2 O microcrystals with cubic, octahedral, and rhombic dodecahedral structures are developed for the electrochemical determination of Pb(II). X. Zheng, X.‐J. Huang, S.‐H. Yu, and co‐workers reveal that Cu 2 O with (111) facets exhibits a larger adsorption capacity and more adsorption energy than that of (100) and (110) facets, which leads to different electrochemical behaviors. On page 2493, the experimental and theoretical results provide a scientific understanding of how the different stripping behaviors are closely related to the facet‐dependent properties of microcrystals.
