Recent advances in tuning crystal facets of polyhedral cuprous oxide architectures

Abstract

Polyhedral inorganic crystals exposed with controllable-index facets is as significant as size, composition, phase and crystallinity in determining their chemical and physical properties. To accurately tune the exposed facets and morphologies of crystals is imperative because a thorough understanding of the formation mechanism and unique performance has significant scientific value. Better understanding of the control of exposed facets would bring about new capability for us to design necessary structures for actual applications. This article presents recent research progress in the development of polyhedral Cu2O architectures, focusing on the expanding of crystal-facet-dependent properties. The challenge and prospects of polyhedral Cu2O architectures are discussed. The present article provides important scientific references and a basis for future work.
