High-efficiency all-solid-state Z-scheme Ag3PO4/g-C3N4/MoSe2 photocatalyst with boosted visible-light photocatalytic performance for antibiotic elimination

Urea-induced supramolecular self-assembly strategy to synthesize wrinkled porous carbon nitride nanosheets for highly-efficient visible-light photocatalytic degradation

“…To further elucidate the degradation mechanism of RhB by UD3 under visible light irradiation, the active species trapping experiments were conducted by using ethylenediaminetetraacetic acid disodium (EDTA-2Na), isopropyl alcohol (IPA) and benzoquinone (BQ), which could act as effective holes (h + ), cOH À and cO 2 À scavengers, respectively. 57,58 As depicted in Fig. 10, the photocatalytic activity was signicantly inhibited by BQ (1 mM) and the decomposition rate of RhB greatly reduced from 98.3% to 12.2%, which suggests that cO 2 À is the major active species of the UD3 sample.…”

Ionic Liquid-Assisted Synthesis of Ag3PO4 Spheres for Boosting Photodegradation Activity under Visible Light

“…The appeared C 1s peak is mainly attributed to the adventitious hydrocarbon from the XPS instrument itself. The high-resolution XPS spectra of Ag 3d in Figure 4b The binding energy of P 2p at 132.75 eV in IL-Ag 3 PO 4 sample (Figure 4c), attributed to the crystal lattice of P 5+ [32], is slightly shifted compared with Ag 3 PO 4 . As shown in Figure 4d, two peaks of O 1s around 532.15 and 530.65 eV are derived from hydroxyl groups on the surface and crystal oxygen in Ag 3 PO 4 , respectively [33].…”

MOF-5-derived ZnO–C nanoparticles combined with α-MnO2 for the efficient degradation of tetracycline under visible light

“…27 In particular, MnO 2 based Z-scheme heterojunctions have been widely studied due to their high electron-transfer efficiency. 28 There are many composite photocatalytic materials that have been studied, such as 2D/2D g-C 3 N 4 /MnO 2 Z-scheme composites with defective Mn 3+ , 29 3D flower-like Bi 2 WO 6 /MnO 2 nanocomposites, 30 α -MnO 2 / α -MoO 3 heterojunctions, 31 and dual Z-scheme core/shell Fe 2 O 3 @MnO 2 nanocube-supported C 3 N 4 . 32 In recent years, the potential of MnO 2 in photocatalysis has been gradually explored.…”
