The orderly nano array is able to improve the light utilization efficiency and has been thought to be a promising way for advancing photocatalysis. The orderly nano array of truncated octahedra Cu2O nanocrystals have been successfully fabricated by the facile solution-based one-step reduction and self assembly method. The results of XRD, SEM and TEM indicate that the Cu2O nano array is successfully assembled on the Si substrate. The photocatalytic activity of the Cu2O orderly nano array is investigated under visible light irradiation, and it is demonstrated to be significantly enhanced after the Cu2O is self assembled orderly. Furthermore, the surface orderly structure of the nano array is considered as the main reason for the enhancement. (C) 2018 Elsevier B.V. All rights reserved.
