![عکس صفحه اول مقاله: Nitrogen-doped titania photocatalysts induced by shock wave Nitrogen-doped titania photocatalysts induced by shock wave](/preview/png/1490991.png)
The nitrogen-doped titania photocatalysts were prepared by shock wave with detonation-driven flyer impact. The samples were shocked at different flyer impact velocities and recovered successfully. The phase composition, light absorption spectra and N doping status of the recovered samples with different flyer velocities and two nitrogen resources containing hexamethylene tetramine (HMT) and dicyandiamide, respectively, were characterized. The absorption edge of the N-doped TiO2 photocatalysts by shock wave was extended to 450 nm corresponding to visible light region. The photocatalytic degradation to rhodamine B of the samples doped with dicyandiamide increased with increasing flyer velocity due to the higher N doping concentration and wider response to visible light.
