One-pot fabrication of novel cuboctahedral Cu2O crystals enclosed by anisotropic surfaces with enhancing catalytic performance

Abstract

For the first time, one-pot solution-phase selective-etching to create cuboctahedral Cu₂O crystals enclosed by both stepped {111} surfaces and smooth {100} surfaces has been demonstrated. Investigation of photocatalytic performances indicates that the stepped cuboctahedral Cu₂O crystals have higher photocatalytic activities than those of the common smooth ones.
