In addition, the stability of Cu₂O is still the main challenging and limiting factor for device applications in real environments. Cu_xO is a mixed semiconductor of CuO and Cu₂O, which is a promising alternative to Cu₂O in device fabrication due to its better stability and photocatalytic efficiency. In this work, Cu_xO nanorods were attached to vertically aligned gold-decorated ZnO nanorods, creating a hierarchical ZnO/Au/Cu_xO nanoforest. In addition, the hierarchical surface shows superhydrophobicity, which can prevent Cu₂O degradation by water and oxygen. Femtosecond time-resolved transient absorption spectroscopy was employed to investigate the electron transfer dynamics in the ZnO/Au/Cu_xO heterojunction. The nanoforest demonstrates enhanced electron mobility, increased lattice match, and higher photocurrent conversion efficiency compared with bare ZnO, Cu_xO, or ZnO/Cu_xO.
