Simultaneous photocatalytic Cr(VI) reduction and phenol degradation over copper sulphide-reduced graphene oxide nanocomposite under visible light irradiation: Performance and reaction mechanism

“…For instance, TiO2/Co-g-C3N4 [16], TbxOy loaded TiO2-oriented nanosheets [17], N-doped TiO2-carbon composite fibres [18], Cu-doped TiO2 nanoparticles modified with 8-hydroxyquinoline [19], carbon nitride loaded into titanium incorporated SBA-15 mesoporous silica (Ti-SBA15-CN) [10], and CdS/TiO2 [20] have been successfully applied for simultaneous removal of metal ions and organic pollutants. For a more efficient use of visible light, various narrow-band gap semiconductor photocatalysts, such as BiVO4 [21], bismuth oxyiodide/reduced graphene oxide/bismuth sulphide (BiOI/rGO/Bi2S3) [22], PANI-sensitized g-C3N4/ZnFe2O4 heterostructure [23] 2O3 -Bi2O2CO3 composite [24], and Au-Pd nanoparticles loaded on g-C3N4/MCM-41 [25] have been investigated for this photochemical process. Nevertheless, it is well-established that some of these photocatalysts have certain disadvantages such as photo-corrosion and instability.…”

Rational Design of 1D Porous Carbon Microtubes Supporting Multi‐size Bi2O3 Nanoparticles for Ultra‐long Cycle Life Lithium‐Ion Battery Anodes

“…[22] As shown in Figure 3e-h, highly resolved lattice spacings of 0.19, 0.28, and 0.32 nm are observed in the high-resolution TEM image, originating from the (222), ( 002) and (201) crystal planes of Bi 2 O 3 , respectively, which certificates Bi 2 O 3 has been successfully prepared. [23] The element mapping (Figure 3i-m) analysis illustrates the coexistence of elements Bi, C and O, which further confirms that the transparent ribbons are 1D porous carbon microtubes, and particles of different sizes are Bi 2 O 3 .…”

Structural, Optical and Photocatalytic Activity of α-Bi2O3/Bi2O2CO3/(BiO)4CO3(OH)2 Ternary Multi-heterojunction Nanoflakes Synthesized via Submerged DC Electrical Discharge in Urea Solution

“…The band groups of CO 3 −2 at ν 1 , ν 2 , ν 3 , ν 4 and ν 1 + ν 4 reveal the formation of Bi 2 O 2 CO 3 . Moreover, the bands at 844 cm −1 and 300 -800 cm −1 are corresponded to Bi-O-C and stretching modes of the Bi-O bonds in Bi 2 O 2 CO 3, and Bi 2 O 3 , respectively 53 .…”
