Facile Fabrication of Bi24O31Br10 Nanosheets with Phosphorus Sulfide Quantum Dots for Highly Photocatalytic Treating Organic Dyes

“…As shown in Figure 4d, Bi 24 O 31 Br 10 belonged to n ‐type semiconductor due to the positive slope of Mott‐Schottky plot. Generally, the CB bottom of an n ‐type semiconductor is very close to the flat band potential ( E fb ) (0.1 V more negative) [44] . Thus, the E fb of Bi 24 O 31 Br 10 was estimated to be about −0.05 eV vs. Ag/AgCl (or 0.15 eV vs. NHE) from the intercept on X axis in Figure 4d.…”

[44] Thus, the E fb of Bi 24 O 31 Br 10 was estimated to be about À 0.05 eV vs. Ag/AgCl (or 0.15 eV vs. NHE) from the intercept on X axis in Figure 4d. The E CB of Bi 24 O 31 Br 10 could be determined to be 0.05 eV vs. NHE.…”

Dye‐Sensitization‐Enhanced Photocatalytic Activity of BiOCl/Sulfur Quantum Dot Heterojunction under Visible‐Light Irradiation

“…As shown in Figure 3d, BiOCl belonged to n‐type semiconductor due to the positive slopes of Mott‐Schottky plot. In general, the bottom of the CB of an n‐type semiconductor is close to a flat band potential ( E fb ) (0.1 V more negative) [54] . For BiOCl, the E fb was estimated to be about −0.39 eV vs .…”

“…In general, the bottom of the CB of an ntype semiconductor is close to a flat band potential (E fb ) (0.1 V more negative). [54] For BiOCl, the E fb was estimated to be about À 0.39 eV vs. Ag/AgCl (or À 0.19 eV vs. NHE) from the intercept of X axis in Figure 3d. So the E CB of BiOCl could be estimated to be À 0.29 eV vs. NHE.…”

An innovative Z-type Sb2S3/In2S3/TiO2 heterostructure: superior performance in the photocatalytic removal of levofloxacin and mechanistic insight

“…[16][17][18] In order to improve its photocatalytic activity and stability in practical applications, many methods have been proposed, such as optimising the structure of TiO 2 and constructing heterostructures. [19][20][21] Since the photocatalytic degradation of antibiotics occurs at the semiconductor-water interface, vertically aligned semiconductor nanoarrays (e.g., nanorods or nanosheets) provide a large number of active sites, reduce carrier diffusion distances and enable multiple light reections between arrays, which can enhance the photocatalytic degradation of LEVs by improving the photo-generated charge separation efficiency of photocatalyst. 22,23 At the same time, it can also reduce the risk of secondary pollution and improve the environmental friendliness of the wastewater treatment process.…”
