Preparation and photocatalytic performance of a magnetically recyclable ZnFe2O4@TiO2@Ag2O p-n/Z-type tandem heterojunction photocatalyst: Degradation pathway and mechanism

Ag Nanoparticle and Ti–MOF Cooperativity for Efficient Inactivation of E. coli in Water

“…To explain this phenomenon, a hypothesis was proposedcertain Ag NPs might have oxidized, resulting in the formation of Ag 2 O . This hypothesis was strongly supported by the previous literature, which reported that the conduction and valence bands of Ag 2 O were −0.03 and +1.49 eV, respectively. As a result, it can be considered that the presence of Ag in Ag/NM125 is in the form of both Ag NPs and Ag 2 O, which results in the formation of a novel heterojunction with NM125 (Figure c).…”

Photocatalytic degradation of RhB in wastewater by zinc ion-doped Bi5O7I

“…Bi 5 O 7 I and the BZ-8 are indirect bandgap semiconductors, n = 4. 33 The bandgaps (E g ) of Bi 5 O 7 I and BZ-8 were calculated to be 3.09 eV and 2.36 eV, respectively, which indicates that by adding Zn 2+ , the valence and conduction bands can be altered, reducing the energy required for electron leaps. The reduction of the band gap drives the absorption of lower energy photons, which results in a broader absorption spectrum and improves the light absorption of the material.…”

A Novel SnO2/ZnFe2O4 Magnetic Photocatalyst with Excellent Photocatalytic Performance in Rhodamine B Removal

“…ZnFe 2 O 4 is a spinel-type n-type semiconductor material that has a narrow bandgap (1.9 eV) and excellent visible light absorption capability and possesses outstanding magnetic properties, making it attracted the attention of domestic and foreign researchers [25][26][27]. ZnFe 2 O 4 can effectively absorb visible light and effectively compound with TiO 2 [28], ZnO [29], Ag nanoparticles [30], and BiOCl [31] et al, which can achieve full coverage of ultraviolet and visible wavelengths.…”
