Abstract

Au nanoparticle sensitized blue TiO2 nanorod arrays as high-performance photocatalysts for efficient Gatifloxacin removal.

Preparation of novel Au-Nb3O7F nanosheets for the photodegradation of tetracycline hydrochloride

“…Obvious photocurrents are present in both the photocatalysts when the irradiation is turned on, and 0.4 Au-Nb 3 O 7 F nanosheets have the greater photocurrent compared to Nb 3 O 7 F. This indicates that the 0.4 Au-Nb 3 O 7 F nanosheets may have the higher separation/migration efficiency of photoexcited carriers compared with Nb 3 O 7 F nanosheets without gold nanoparticles. This finding indicates that the combination of the Au nanoparticles as well as the Nb 3 O 7 F nanosheets may be benefit for the charge separation, leading to the improved photocatalytic performance ( Liang et al, 2020 ; Guo et al, 2023 ).…”

“…This optical phenomenon is likely attributed to the LSPR effect, which is believed to be closely related to the Au nanoparticles, and the largest absorption peak at 520 nm of 0.4 Au-Nb 3 O 7 F nanosheets was attributed to the Au NPs. The 0.4 Au-Nb 3 O 7 F nanosheets possess strong LSPR effect and are expected to an excellent candidate for visible light photodegradation ( Cui et al, 2022 ; Guo et al, 2023 ; Zhao et al, 2024 ). In addition, the bandgap calculated by the Tauc’s plot is shown in Supplementary Figure S8 .…”
