摘要:A green and efficient photocatalyst based on C and N co-doped titanium based nanorods (NRs) was prepared by facile hydrothermal synthesis and interlaminar bonding interaction between layered and tetramethylammonium hydroxide (TMAH). TMAH as one of quaternary ammonium-based compounds was used as the doping source of C and N elements. The results showed that C and N co-doping did not affect the anatase crystal structure of TiO2 NRs. C, N-TiO2 NRs showed excellent photocatalytic activity for degrading methyl orange under simulated sunlight irradiation. In particular, the 20:1 TiO2 NRs catalyst showed the best catalytic performance, showing efficient photocatalytic rate of 90%. The photocatalytic reaction kinetics of undoped and doped catalysts was also studied. In addition, reactive species (RSs) experiments showed that hydroxyl radical (OH), superoxide radical anions (O2-) and photogenerated holes (h+) were major active species during the photocatalytic process. The mechanisms of the electrostatic attraction and potential photocatalytic degradation were proposed and discussed. © 2020 The Author(s). Published by IOP Publishing Ltd.
