Highly efficient photocatalytic organic dyes degradation based on 1D magnetic Bi2Fe4O9/C@AgBr composite

“…Compared with the Bi 2 Fe 4 O 9 /C fibers (k = 0.027 min À1 ), Bi 2 Fe 4 O 9 /C@AgBr photocatalyst revealed the higher rate constant (k = 0.053 min À1 ), determining that as-prepared catalyst possesses the excellent catalytic efficiency.

S-Scheme In2O3 Nanoparticle/BiOBr Nanoplate Heterojunctions for Improved Photocatalytic Dye Degradation and Cr(VI) Reduction

“…16 Figure 3b shows the Br 3d XPS spectrum for pristine BiOBr; the XPS signal at a binding energy of about 69.04 eV (Br 3d 3/2 ) and 68.01 eV (Br 3d 5/2 ) arises from Br − anions in the lattice of the sample. 25 In addition, the peak for O 1s of BiOBr (Figure 3c) could be fitted into two broad peaks centered at ∼529.73 eV (O L ) and ∼531.35 eV (O V ), which are ascribed to the oxygen atoms in the crystal lattice and adsorbed hydroxyl groups of oxygen vacancy, 51 respectively. Particularly, it is found that the binding energy positions of Bi 4f, Br 3d, and O 1s for the 8% In Bare BiOBr presents an irregular sheet shape with a smooth and clean surface (Figure 4a).…”

“…It is found that an interplanar spacing of ∼0.282 nm for the substrate coincides with the (102) plane of BiOBr. 25 The small nanoparticles attached on the BiOBr nanoplate surface exhibit a clear lattice fringe with a spacing of ∼0.286, ∼0.238, and ∼0.231 nm, corresponding to the (104), (440), and (420) crystal planes of In 2 O 3, 55,56 respectively. Such results further demonstrate the production of an intimate heterojunction structure between In 2 O 3 and BiOBr.…”

Study on the relationship between Bi2S3 with different morphologies and its photocatalytic hydrogen production performance

“…Due to the largest BET specific surface area, larger pore size and larger pore volume, Bi 2 S 3 nanotubes do not only have more channels to facilitate the transmission of substances, but also provide more space for intermediate products. A larger specific surface area, larger average pore size and larger mesoporous volume provide many favorable advantages, including favoring the adsorption of water molecules, facilitating the transport of photogenerated carriers and providing more reactive active sites, thus promoting the photocatalytic performance of the material (He et al 2021;Du et al 2021;Wang et al 2020). As mentioned above, the low PL intensity may correlate with the efficient charge transfer in the Bi 2 S 3 nanotubes with the largest BET surface area, pore size and pore volume, thereby confirming the prevention of the direct recombination of electrons and holes.…”
