Nanosheets loaded on tetrahedral surfaces form a Z-type Bi₂MoO₆/γ-Bi₂O₃ heterojunction to enhance the photocatalytic degradation activity of lomefloxacin and Rhodamine B

Abstract

Nanosheets loading on tetrahedral surfaces of a Bi2MoO6/γ-Bi2O3 heterojunction forming a Z-type energy band to enhance the photocatalytic degradation activity.

Fast photocatalytic degradation of rhodamine B using indium-porphyrin based cationic MOF under visible light irradiation

“…The degradation of 5.19% of MO and 5.41% of MB occurred under 500 nm light irradiation under the same conditions. As shown in Table 1, the In( iii )–porphyrin MOF in this work is comparable with other reported MOFs, COFs and even inorganic semiconductors, 35–50 enabling it a promising photocatalyst for water-pollutant degradation. In comparison, the free TPyP exhibits low photocatalytic performance toward the above three dyes: degradation of 68.95% of RhB, 10.25% of MO and 64.59% of MB after 60 min (Fig.…”

Construction of a novel S-type γ-Bi2O3/CeO2 heterojunction for highly efficient photocatalytic degradation of antibiotics

“…A Z-type heterojunction was constructed using g-Bi 2 O 3 with Bi 2 MoO 6 and BaTiO 3 for degrading lomefloxacin and tetracycline. 23,24 Nevertheless, the improvement of the photocatalytic efficiency was only 46% and 31%. The phase transition between a-Bi 2 O 3 and g-Bi 2 O 3 brought a new transfer channel in the titanate heterojunction, but the increment quantity of photocatalytic efficiency was only 30% and 21%.…”

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.…”
