Preparation of Bi/BiOBr sensitized titania nanorod arrays via a one-pot solvothermal method and construction of kanamycin photoelectrochemical aptasensors

Abstract

In this work, a photoelectrochemical (PEC) aptasensor for detecting kanamycin (KAN) was designed based on aptamer modified Bi/BiOBr/ titania nanorod array (TiO2 NRA). Bi/BiOBr was loaded onto TiO2 NRA via...

Iron doped BiOBr loaded on carbon spheres for improved visible-light-driven detoxification of 2-chloroethyl sulfide

“…16,17 Among them, BiOBr was paid much attention by scientists due to its appropriate band gap and advantages of non-toxicity, low cost and environmental friendliness. [18][19][20][21][22][23] In addition, it has a unique structure in which the [Bi 2 O 2 ] 2+ plates are sandwiched between the double Br − layers, which leads to easy breaking of the Bi-O bond to produce oxygen vacancies. 24 The oxygen vacancies improve the separation and transport of photogenerated charges which improve photocatalytic activity.…”

Bi/BiOI/carbon quantum dots nano-sheets with superior photocatalysis

“…To the best of our knowledge, the SPR effect would improve the photocatalytic performance of the photocatalyst. 3,[43][44][45] Bi plays two main roles in photocatalysis. On the one hand, Bi can be used as an electron donor and conductor, promoting the separation of electron-hole pairs.…”

“…On the other hand, its SPR effect could prompt the photocatalyst to harvest more light absorption. 2,44 However, as far as we know, no existing report is about the synthesis of the Bi/BiOI/CQDs ternary material. Therefore, the photocatalytic performance of Bi/BiOI/CQDs nano-materials is evaluated by photo-degradation of rhodamine (RhB).…”
