Photocatalytic Ag Nanoparticle Growth Induced Oxygen Vacancy Formation on Few-Layered BiOBr Nanosheets and Enhancements of ·O2– Generation Toward Tetracycline Photodegradation

“…This further demonstrates that PG-Ag/FL-BiOBr-NSs have the highest activity for TC degradation among the photocatalysts investigated in this work. In particular, the degradation rate constant of PG-Ag/FL-BiOBr-NSs is higher than that of many photocatalysts reported, such as Bi 2 WO 6 /CoIn 2 S 4 , Ag 3 VO 4 /LDH, and ZnO/γ-Fe 2 O 3 (the detailed comparison is given in Table S1). It well suggests that PG-Ag/FL-BiOBr-NSs are efficient catalysts for TC degradation.…”

Insight into the enhanced photocatalytic activity mechanism of the Ag3VO4/CoWO4p–n heterostructure under visible light

“…The diffraction peaks of the pristine Ag 3 VO 4 at 2 θ = 19.3, 30.9, 32.4, 36.1, 38.9, 51.1 and 54.0° were assigned to the (011), (−121), (121), (220), (022), (132) and (331) crystal planes of the Ag 3 VO 4 monoclinic structure (JCPDS no. 43-0542), 29 respectively. At the same time, all the diffraction peaks of the AgCoO composites were absolutely indexed to the peaks of the pristine Ag 3 VO 4 and pristine CoWO 4 , in which no other crystalline phases were observed.…”

Construction of Ultrafine Ag2S NPs Anchored onto 3D Network Rodlike Bi2SiO5 and Insight into the Photocatalytic Mechanism

“…For the pristine Ag 2 S, the high-resolution Ag 3d spectrum had two individual peaks at 373.5 eV (Ag 3d 3/2 ) and 367.4 eV (Ag 3d 5/2 ) assigned to Ag + , while the two peaks at 161.5 and 159.8 eV, corresponding to S 2p 1/2 and S 2p 3/2 , were due to S 2– in Ag 2 S . Talking about the virgin Bi 2 SiO 5 , the high-resolution Bi 4f spectrum had two peaks at 164.5 eV (Bi 4f 5/2 ) and 159.2 eV (Bi 4f 7/2 ) with an energy gap of 5.3 eV assigned to Bi 3+ , while the Si 2p spectrum exhibited a strong peak at 101.7 eV, which was characteristic of Si 4+ .…”

“…The presence of the C 1s peak was ascribed to adventitious carbon as the reference for calibration. 16,18 For the pristine Ag 2 S, the high-resolution Ag 3d spectrum had two individual peaks at 373.5 eV (Ag 3d 3/2 ) and 367.4 eV (Ag 3d 5/2 ) assigned to Ag + , 26 while the two peaks at 161.5 and 159.8 eV, corresponding to S 2p 1/2 and S 2p 3/2 , were due to S 2− in Ag 2 S. 27 Talking about the virgin Bi 2 SiO 5 , the highresolution Bi 4f spectrum had two peaks at eV (Bi 4f 5/2 ) and 159.2 eV (Bi 4f 7/2 ) with an energy gap of 5.3 eV assigned to Bi 3+ , 28 while the Si 2p spectrum exhibited a strong peak at 101.7 eV, which was characteristic of Si 4+ . 14 And the fitting of the O 1s spectrum showed four peaks at 532.5, 531.4, 530.3, and 529.0 eV, which were attributed to the surface-adsorbed oxygen (O ads ), defect oxygen (O v ), Bi−O, and Si−O, respectively.…”
