Designated-Tailoring on {100} Facets of Cu₂O Nanostructures: From Octahedral to Its Different Truncated Forms

Figure 11

A schematic illustration of the proposed particle growth mechanism and reaction pathways that lead to the formation of Cu₂O crystals with different polyhedral shapes. As the essence of our synthesis, the precursors with different properties can be reduced by C₆H₁₂O₆ to form Cu₂O particles, which subsequently aggregate to form different initial structures. Subsequently, these initial structures will grow into various polyhedral forms through the synergic effect of oriented attachment and ripening mechanism, which can modify the ratio (𝑅) between the growth rates along the ⟨100⟩ and ⟨111⟩ directions.
