Nanowire Arrays: Hierarchical Nanowire Arrays Based on ZnO Core−Layered Double Hydroxide Shell for Largely Enhanced Photoelectrochemical Water Splitting (Adv. Funct. Mater. 5/2014)

Abstract

Well-aligned hierarchical nanoarrays containing a ZnO core and layered double hydroxide (LDH) nanoplatelet shell are synthesized by M. Wei and co-workers via a facile electrosynthesis method. The resulting ZnO@CoNi–LDH core–shell nanoarray material exhibits promising behavior in photoelectrochemical (PEC) water splitting, giving rise to a largely enhanced photocurrent density as well as stability. On page 580, a facile and costeffective strategy is provided for the fabrication of hierarchical nanoarrays which can be potentially used in energy storage and conversion.
