Nanostructured SnO2/TiO2 hybrid materials can be promising anode materials for lithium ion batteries (LIBs). We herein report a novel and energy-saving photodeposition approach to fabricate SnO2/TiO2 composite nanotubes. In the photodeposition process, Sn2+ ions are oxidized to SnO2 by the photogenerated holes, thus SnO2 nanoparticles are deposited onto both the inner and outer walls of TiO2 nanotubes...
Transition metal oxide nanostructures are one of current investigation focuses for energy storage applications. We herein report a novel template-free electrochemical approach to fabricate Ni(OH)2/NiO/Ni composite nanotube array films on the nickel substrate. The inner diameter of the composite nanotubes can be effectively tuned by tailoring the concentration of Cu2+ in the precursor solutions. The...
