Seed-mediated synthesis of polyhedral 50-facet Cu₂O architectures

Highly symmetric polyhedral 50-facet Cu₂O homogeneous structures enclosed by 24 high-index {211} facets, and 8 low-index {111} facets, 6 low-index {100} facets and 12 low-index {110} facets have been synthesized via a facile seed-mediated solution phase route. The formation of these polyhedral architectures not only provides an innovative approach to design and synthesize more and more novel polyhedral shapes to further enrich the current morphologies of Cu₂O crystals, but also offers a good opportunity to understand the fundamental significance of high-index facets for enhancing the catalytic degradation of methyl orange.
