All-solid Z-scheme Bi/γ-Bi2O3/O-doped g-C3N4 heterojunction with Bi as electron shuttle for visible-light photocatalysis

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

“…The separation efficiency of the photogenerated electrons and holes is poor in pure phase Bi 2 O 3 and Bi 2 MoO 6 . 31,32 To solve this problem, the construction of a heterojunction is a common method to enhance the separation efficiency of the charge carriers such as α/β/γ-Bi 2 O 3 33 and Bi 2 MoO 6 /GQDs/MoS 2 . 34 The Bi 2 O 3 and Bi 2 MoO 6 are Bi-based semiconductors and therefore it should be feasible to use them in a composite.…”

Bismuth-Based Z-Scheme Heterojunction Photocatalysts for Remediation of Contaminated Water

“…The catalyst exhibits a broad light absorption range due to the all-solid heterojunction formed between Bi 2 O 3 and EtCN with Bi acting as an electron shuttle as shown in Figure 8. 170 Volatile Organic Compound (VOC) Degradation. Chemicals known as volatile organic compounds (VOCs) are frequently released from the burning of fuels, industrial production of waste gases, and the use of decorative paints and photochemical pollution.…”

“…It has been shown that Bi/ γ -Bi 2 O 3 /EtCN heterojunctions are more active in photocatalytic degradation of bisphenol A (BPA) than g -C 3 N 4 and ethanol assisted carbon nitride (EtCN), with a degradation rate 15.67 times higher than g-C 3 N 4 . The catalyst exhibits a broad light absorption range due to the all-solid heterojunction formed between Bi 2 O 3 and EtCN with Bi acting as an electron shuttle as shown in Figure …”

Cellulose-templated Bi2SiO5nanorods with enhanced UV/vis light utilization efficiency for high-performance photocatalytic degradation of organic contaminants

“…The morphology of rod-like Bi 2 -SiO 5 nanoparticles allowed the photocatalysts to efficiently utilize sunlight, which further broadened the response range of the photocatalysts to generate electron-hole pairs. 43 It can be seen that a unique morphology may endow photocatalysts with a distinctive bandgap, which may be conducive to the photocatalytic performance. 44…”

“…The novel morphology and small nanoscale size of the photocatalysts were expected to endow them with excellent comprehensive light utilization efficiency. 43 Herein, different kinds of light irradiation were employed to evaluate the CrystEngComm Paper comprehensive light utilization efficiency of the CBSO-600 sample in the RhB photodegradation process (Fig. 6e).…”
