Enhanced photoelectrocatalytic performance of temperature-dependent 2D/1D BiOBr/TiO 2-x nanotubes
Source abstract
Abstract
Abstract A p-n junction with oxygen vacancy and excellent visible light response based on 1D TiO2-x nanotubes and 2D BiOBr nanosheets was prepared successfully. BiOBr nanosheets are well distributed on the outer walls of TiO2-x nanotubes by chemical bath deposition method. The fabricated intimately connected interfacial p-n junction between 2D BiOBr nanoplates and 1D TiO2-x nanotubes offers an interfacial nanochannel, which can promote efficient interfacial charge migration and separation. The construct of TiO2-x extends the photoresponse to visible light due to the introducing of oxygen vacancy. The B/T-80 °C exhibits excellent visible light photoelectrocatalytic activities and stable performance for Rhodamine B (λ = 420 nm), which is caused by the enhanced visible light response, the intimately connect of 2D BiOBr and 1D TiO2-x, and the formation of p-n junction. Furthermore, the quantity and dimension of BiOBr nanoplates decorated on TiO2-x nanotubes has been well controlled by adjusting the dipping temperature.
