Construction of direct Z-scheme BiOBr/CuI heterojunction for boosting photocatalytic degradation of phenol

Abstract

In this work, direct Z-scheme BiOBr/CuI heterojunctions are successfully synthesized using a simple solvothermal method for the first time. The photocatalytic activity of BiOBr/CuI composites catalysts is evaluated by the...

Layered Double Hydroxides: Recent Progress and Promising Perspectives Toward Biomedical Applications

“…[ 39 , 61 , 62 , 63 ] Notably, the differences in composition and size have little effect on the biocompatibility of LDHs, [ 64 , 65 ] which provides a guarantee for their safe application as biomedical materials. Second, LDHs have characteristics such as interlayer ion exchangeability, [ 38 , 39 ] high specific surface area, [ 66 , 67 ] and adjustable interlayer spacing, [ 68 ] which make them efficient carriers for drug molecules, [ 69 ] genes, [ 70 , 71 ] and bioactive molecules, [ 70 , 72 , 73 ] with the ability to achieve ultra‐high loading capacity. [ 15 , 74 ] Moreover, LDHs as carriers can also provide good protection for the drug molecules they carry, achieving the controlled release effect and effectively avoiding the resistance and side effects caused by repeated administration.…”

Synthesis of H2O2 to Self-Catalyzed Generation of •OH over ZnO/CuI/Cu Foam Electrode for the Self-Fenton Cleaning of Wastewater

“…18 As a photocatalyst, CuI has received much attention in recent years for degrading organic pollutants in water. 19,20 CuI is combined with photocatalysts such as BiOBr, 21 g-C 3 N 4 22 and FePO 4 23 to form heterojunctions, which exhibit remarkably improved photocatalytic activity for degrading organic pollutants in water. The CuI/BiOI shows enhanced photocatalytic activity, 24,25 and the CuI/g-C 3 N 4 exhibits efficient photocatalytic hydrogen evolution.…”

“…Therefore, researchers prepared many ZnO-based photocatalysts by ion doping, metal deposition and heterostructure construction, such as Cr-doped ZnO, Cu-doped ZnO, Ag/ZnO, Pt/ZnO, MoS 2 /ZnO, Bi 2 O 3 /ZnO and ZnO/Ti 3 C 2 .

Mechanochemical preparation of graphdiyne (CnH2n−2) based Ni-doped MoS2 S-scheme heterojunctions with in situ XPS characterization for efficient hydrogen production

“…It can be seen that the k et values of samples EY, NiS, MoS 2 , GDY, NM-3, and NMG-20 gradually increase, which proves the formation of S-scheme heterojunctions from the side. [61][62][63]…”
