In recent years, considerable attention has been focused on various polyhedron-based branched particles due to their fundamental significance and widespread potential application. However, knowledge of the original nature and growth mechanisms for these complicated structures is still limited. In this paper, polyhedron-based branched Cu2O microcrystals have been prepared via an electrodeposition process without any surfactant at room temperature. The electron diffraction pattern of the branched Cu2O microcrystals can be indexed as a single crystal, as many other polyhedron-based branched crystals exhibit. By carefully analyzing the intensities of the diffraction spots we, for the first time, conclude that the single-crystal-like Cu2O branched particles are in fact twinning crystals. It could be anticipated that the crystal twinning (or the stacking fault) could be popular in the single-crystal-like branched particles.
