文摘

Herein SnO₂/Fe₂O₃ heterojunction nanotubes are prepared by a facile electrospinning technique. The heterojunction nanotubes with a diameter of about 200 nm uniformly distribute SnO₂ and Fe₂O₃ nanocrystals and present the obvious interfaces between them, which form perfect SnO₂/Fe₂O₃ nano-heterojunctions. A possible mechanism based on self-polymer-templates is proposed to explain the formation of SnO₂/Fe₂O₃ heterojunction nanotubes. The heterojunction nanotubes show high photocatalytic activity for the degradation of RhB dye under visible light irradiation. The prepared SnO₂/Fe₂O₃ heterojunction nanotubes can also be applied to other fields such as sensor, lithium-ion batteries.
