文摘

N-doped TiO2 nanorod (NTR) has Ti3+ and oxygen vacancy defect states on the surface. Longer NTR has higher photoactivity for thiol molecules oxidation and CO conversion. NTR can further oxidize −SH to sulfonic species unlike undoped TiO2 nanorod. Greater number of defect states on NTR contribute to improved photocatalytic activity.
