The long‐range ordered cuprous oxide nanostructured superlattice ( Lα‐Cu 2 O ) was synthesized using sodium dodecyl sulfonate ( SDS ; C 12 H 25 SO 3 Na ) as supermolecular template in water‐ethanol media via a facile reflux method. CuCl 2 , glucose and NaOH served as Cu source, reductant and precipitant, respectively. X‐ray diffraction analysis showed that Cu 2 O is the sole inorganic phase in Lα‐Cu 2 O . Transmission electron microscopy further observed and proved this 2.7‐nm period of regular nanostructured superlattice arrays detected and calculated by small angle X‐ray diffraction (2.71 nm). Field emission scanning electron microscopy exhibited that Lα‐Cu 2 O presents granular particles of around 700 nm. In contrast, the template free Cu 2 O ( TF‐Cu 2 O ) presents no ordered nanostructure and shows polyhedral morphology. The possible mechanism of SDS serving as soft template was proposed and discussed in thermodynamics.
