Facile electrochemical synthesis of ZnO/PbSe heterostructure nanorod arrays and PbSe nanotube arrays

► The ZnO/PbSe core-shell nanorod arrays were fabricated by a two-step electrodeposition method from aqueous solution for the first time. ► The absorption spectrum of ZnO/PbSe shows visible light absorption from 500 nm to 650 nm due to the PbSe coating. ► PbSe nanotube arrays were obtained by immersing the ZnO/PbSe core-shell nanorods arrays in hydrochloric acid for 10 min.
