Construction of novel In2S3/Ti3C2 MXene quantum dots/SmFeO3 Z-scheme heterojunctions for efficient photocatalytic removal of sulfamethoxazole and 4-chlorophenol: Degradation pathways and mechanism insights

Robust degradation of tetracycline antibiotic through recyclable Fe3S4/Ti3C2MXene composites

“…Most anions frequently compete with pollutants for oxidative species such as ˙OH radicals, reducing catalytic effectiveness. 41 Here, specific inorganic anions (Cl − , NO 3 − , PO 4 3− , and CO 3 2− ) were selected to assess their influence on TC degradation in the Fe 3 S 4 /Ti 3 C 2 MXene + H 2 O 2 system. The corresponding degradation results are illustrated in Fig.…”

“…Most anions frequently compete with pollutants for oxidative species such as ˙OH radicals, reducing catalytic effectiveness. 41 reacting with ˙OH to produce weakly oxidizing PO 4 ˙2− or causing a minor increase in solution pH, which is not conducive for TC degradation. Furthermore, the introduction of CO 3 2− considerably decreases the degradation efficiency, likely because CO 3 ˙− significantly alters the solution pH and obstructs ˙OH generation.…”

Fast Interfacial Carrier Dynamics Modulated by Bidirectional Charge Transport Channels in ZnIn2S4‐based Composite Photoanodes Probed by Scanning Photoelectrochemical Microscopy

“…In the transmission electron microscopy (TEM) image of MQDs/ZIS, the lattice fringes with a spacing of 0.26 nm correspond to the (0110) crystal planes of MQDs (Figure S4b). [30] Subsequently, FO nanodots with around 9.8 nm (Figures S5) were assembled onto the surface of ZIS NSs through a solvothermal reaction. The SEM images (Figures S4d-f) reveal a uniform and dense coating of FO nanodots on the surface of ZIS NSs, with an increased concentration of the precursor Fe(NO 3 ) 3 •9H 2 O leading to enhanced growth and aggregation of FO nanodots.…”

MXene-based nanocomposites: emerging candidates for the removal of antibiotics, dyes, and heavy metal ions

“…The higher photocatalytic activity of the synthesized photocatalysts toward NOR degradation may be due to the presence of –OH, O, –F, and –NH functionalities on the surface of the photocatalyst material. Kumar et al 161 prepared a novel In 2 S 3 /Ti 3 C 2 MXene quantum dots/SmFeO 3 heterojunction nanohybrid composite using the facile sol–gel method. The as-prepared nanohybrid heterojunction was used for the photocatalytic degradation of SMX antibiotic drug from the water bodies.…”
