Facile synthesis of Fe/Bi2SiO5 nanocomposite with enhanced photocatalytic activity for degradation of 17β-Estradiol(E2)

A review on hospital wastewater treatment: A special emphasis on occurrence and removal of pharmaceutically active compounds, resistant microorganisms, and SARS-CoV-2

“…However, most of these studies are lab-scale and conducted on synthetic wastewater. As a result, more research is required on these technologies before they can be implemented in the field [166] , [174] , [208] , [209] .…”

Ultrasonic Preparation of PN For The Photodegradation of 17ß-Estradiol In Water And Biotoxicity Assessment Of E2 After Degradation

“…However, it may be observed that the photodegradation of E2 is enhanced for 0.5%PN, but further increase in the PN content would decrease the degradation performance. This may be attributed to the fact that PN as an electron acceptor could prevent electronhole recombination caused by TiO 2 [31][32][33][34]. Moreover, h + could react with water and oxygen to generate •OH to eliminate E2, as shown in equation B(2)-B(6).…”

“…However, O 2 was required to be supplied continuously during this process, inevitably leading to a higher cost for practical applications. Li et al [31] and Fernandez et al [32] reported a degradation e ciency of 99.5% and 90% when Fe-Bi 2 SiO 5 and P25 were utilized to decompose E2 at 3 ppm and 1 ppm in aqueous solution, respectively. According to Langmuir-Hinshelwood mechanism, these higher e ciencies were likely attributed to the lower E2 concentration.…”

2D/2D Bi2WO6/Protonated g-C3N4 step-scheme heterojunctions for enhancing the photodegradation of 17β-estradiol: promotional role of electrostatic interaction

“…19 Li et al synthesized Fe-Bi 2 SiO 5 catalysts for E2 removal by combining a hydrothermal method and impregnation technique. 20 These photocatalysts could initiate the photodegradation of E2 under visible light, but the photogenerated carriers (e − and h + ) still tended to recombine because the e − and h + were in the same component. To solve these critical problems, many researchers have concentrated on the construction of heterojunctions, which can promote the separation of photogenerated carriers and integrate the respective advantages of each component.…”
