Magnetically separable BiOBr/Fe3O4@SiO2 for visible-light-driven photocatalytic degradation of ibuprofen: Mechanistic investigation and prototype development

Integration of Polydopamine and Fe3O4 Nanoparticles with Graphene Oxide to Fabricate an Efficient Recoverable Catalyst for the Degradation of Sulfadiazine

“…The applied organic scavengers were t-butanol, benzoquinone, and EDTA (10 mM) for quenching scavenging • OH, O 2 •− , and h + , respectively. 52,53 As can be seen from Figure 6b, without adding any scavenging additive, the DE% was found to be 93.1%. Furthermore, the sonocatalyst became passive toward the SDZ molecules in the presence of the scavenger molecules due to the surface occupation, preventing the generation of • OH radicals.…”

“… The mechanism for SDZ degradation using the M-GO–PDA nanocomposite was investigated in the presence of inorganic and organic quenching reactants for the • OH radicals as the main oxidizing species in the sonocatalytic process. The applied organic scavengers were t-butanol, benzoquinone, and EDTA (10 mM) for quenching scavenging • OH, O 2 •– , and h + , respectively. , As can be seen from Figure b, without adding any scavenging additive, the DE% was found to be 93.1%. Furthermore, the sonocatalyst became passive toward the SDZ molecules in the presence of the scavenger molecules due to the surface occupation, preventing the generation of • OH radicals.…”

Degradation of Atenolol in a Rectangular Staircase Photocatalytic Reactor with Immobilized ZnO

“…The experimental data of the recirculation flow and initial concentrations of the degradation kinetics of ATL were used for validation of the modified GMBE simulated by Matlab.2011 according to Eqs. (16) and (17), respectively. The obtained results are illustrated in Fig.…”

“…Many studies are available on the development of various types of solar photocatalytic reactors, where the semiconductor catalyst is generally in the form of powder suspended in a liquid medium [12][13][14][15][16]. The inconvenience of this as a large-scale approach is the catalyst recovery step from the solution at the end of operation.…”

Construction of a novel two-dimensional AgBiO3/BiOBr step-scheme heterojunction for enhanced broad-spectrum photocatalytic performance

“…However, BiOBr possesses common problems like most semiconductor materials including poor light absorptivity and high recombination efficiency. 18,19 To overcome these issues, new synthesis methods have been employed. For example, Zhang prepared ultra-thin BiOBr nano-roundels in water-in-oil emulsion microspheres by a solvothermal route, which results in materials with excellent photocatalytic activity, and the degradation rate of organics reached as high as 99.2%.…”
