Novel La3+/Sm3+ co-doped Bi5O7I with efficient visible-light photocatalytic activity for advanced treatment of wastewater: Internal mechanism, TC degradation pathway, and toxicity analysis

Synthesis and application of type-II heterojunctions based on CdS and g-C3N5 for efficient photocatalytic degradation of antibiotics

“…P2 and P3 could further transform during photocatalytic oxidation to generate P4 ( m / z = 349). 66,67 For degradation pathway 3, TCH was decomposed to P5 ( m / z = 417) successively by losing two methyls under the oxidation of ˙O 2 − . 68 Finally, these intermediates can be degraded and converted into inorganic ions such as CO 2 and H 2 O under further oxidation.…”

Photocatalytic degradation of RhB in wastewater by zinc ion-doped Bi5O7I

“…23 No new characteristic diffraction peaks (zinc or zinc compounds) were observed in the XRD pattern after the addition of Zn 2+ , indicating that all of the samples consisted of the Bi 5 O 7 I phase. Although no diffraction peak of Zn 2+ was observed, the displacement of the diffraction peak indicates a unit cell change induced by ion doping, 24 suggesting that Zn 2+ was successfully introduced into the Bi 5 O 7 I lattice. The introduction of a zinc source did not trigger heterojunction formation or dramatic lattice distortion.…”

In situ fabrication of a 2D/2D WO3/Bi5O7I S-scheme heterojunction with enhanced spatial charge separation and tetracycline degradation

“…To overcome these deficiencies, many surface-regulating strategies have been proposed, such as increasing surface area, facet engineering, 9,[14][15][16] defect construction, [17][18][19] doping of heteroatoms, 20,21 and constructing heterojunctions. 22,23 Fabricating two-dimensional (2D) photocatalysts with a high surface area is an efficient way to increase the density of active sites and enlarge the interface between photocatalysts and electrolytes, where the depletion region is generated for better charge separation.…”
