Abstract BACKGROUND Preparing catalysts with heterojunction structures is a strategy to achieve efficient charge separation and transfer of charges enhance photocatalytic activity photocatalysts. To optimize the graphitic carbon nitride (g‐C 3 N 4 )‐based photocatalysts, Bi 2 MoO 6 @ 2D g‐C catalyst was prepared. RESULTS nanopiece@2D nanoflake composites in different proportions were prepared by hydrothermal method. The materials characterized various modern instrumental analyses, their ability decompose water degrade rhodamine B under visible light irradiation tested. Compared pure nanopiece nanoflake, hydrogen evolution rate nanopiece@g‐C (1:10) composite highest, at 4847 μmol h −1 g . (3:10) exhibited significantly enhanced degradation for organic dye removal due formation an excellent improve migration efficiency photogenerated carriers. CONCLUSION O 2− • OH two main active species B. formed , which accelerated efficiency, thereby enhancing activity. © 2023 Society Chemical Industry (SCI).

In this study, magnetic (Fe)-loaded biochar was successfully prepared by a simple impregnation pyrolysis method. Meanwhile, its degradation capability and mechanism for typical antibiotic metronidazole (MNZ) were systematically investigated under different conditions. The characterization of the synthesized material showed that specific surface area, pore diameter, volume changed significantly. Also, functional groups metal element Fe introduced on biochar, leading to better activate peroxymonosulfate (PMS). experiments removal MNZ in Fe-BC/PMS system can reach up 95.3% 60 min optimal Free-radical capture there several active species •OH, SO4•−, •O2−, 1O2 present catalyst synergistically degrade MNZ, among which SO4•− played major role; it also found be easily recycled still effective after uses. Further, main pathways include nitrohydroxylation, hydroxyethyl group deletion, carboxylation amino demethylation, oxidation, carboxylation. It is obvious magnetic-loaded Fe-BC, generated from waste rape straw crops, shows high catalytic performance pollutant degradation, providing an insight into recycling potential biomass field removal.
