Construction of plasmonic Bi/Bismuth oxycarbonate/Zinc bismuth oxide ternary heterojunction for enhanced charge carrier separation and photocatalytic performances

Construction of type II ZnBi2O4/g-C3N4 heterojunction photocatalysts for efficient degradation of acid red B

“…Combined with the above band gap E g of g-C 3 N 4 and ZnBi 2 O 4 , the conduction band E CB of g-C 3 N 4 and ZnBi 2 O 4 are calculated as −0.77 eV and −1.35 eV by the equation E CB = E VB − E g . 59…”

Photocatalytic Enhancement Strategy with the Introduction of Metallic Bi: A Review on Bi/Semiconductor Photocatalysts

“…The three-dimensional (3D) form of Bi is usually represented as Bi spheres in catalyst systems and 3D Bi/semiconductor photocatalysts have numerous applications in the field of environmental purification. [79][80][81] For instance, Li et al [47] synthesized Bi nanospheres on graphene oxide (GO) through a solution-based sonication method. The obtained Bi-NPs@GO composites can be used as robust direct plasmonic photocatalysts for NO removal.…”

“…Their results demonstrated that the degradation efficiency of magnetic bentonite/BiOBr-Bi was 2.3 folds higher than pure BiOBr, which was mainly attributed to the synergistic contribution of Bi nanoparticles, oxygen vacancy, and magnetic bentonite. Zhang et al [80] obtained Bi/ Bi 2 O 2 CO 3 /ZnBi 2 O 4 prepared through a solvothermal reaction with more than 80 % removal of tetracycline, much higher than pure Bi 2 O 2 CO 3 and pure ZnBi 2 O 4 . The effects of hydrothermal reaction time were optimized, and free-radical trapping experiments indicated that * O 2 À and * OH were the key reactive species.…”

Flower-like Ag2WO4/CeO2 heterojunctions with oxygen vacancies and expedited charge carrier separation boost the photocatalytic degradation of dyes and drugs

“…34 Whether the photoinduced carriers can be separated efficiently and quickly is one of the key factors affecting the photocatalytic process. 35 We investigated the photodegradation mechanism using PL, EIS, and nitrogen adsorption/desorption. As shown in Fig.…”
