In this work, a novel FeNi2S4/TiO2–x nanocomposite was prepared by facile hydrothermal synthesis, then comprehensively characterized multitechnique approach, and subsequently employed for round-the-clock (light dark) removal of rhodamine B. Superior improvement the morphological thermal properties due to use sodium dodecyl sulfate investigated. An l-ascorbic acid-assisted photo-Fenton catalyst can be effectively complete B at 30 min using 10 W white-light-emitting diode (LED) source under wide range operating conditions compared other reported catalysts. The obtained results show significant synergism between components, which makes total RhB much better than when each used alone. This study presents approach designing sustainable multifunctional with reusability, high catalytic activity, environmental friendliness. Due photocatalytic in presence hydrogen peroxide ascorbic acid visible light, there is potential generate more electron/hole carriers hydroxyl radicals (•OH).

The Fenton-like reaction has been widely used for environmental modification. However, improvement of the catalytic efficiency is still a challenge. In this study, series core-shell-shaped catalysts (FeNC-x, x presents calcination temperature) was fabricated through pyrolysis Fe-based metal-organic frameworks (Fe-MOF). Fe species were encapsulated by N-doped carbon materials and changed from Fe3O4 to Fe3C, α-Fe, Fe-N4 with temperature increasing 500 800 °C. Simultaneously, electron density atom obviously increased. FeNC-650 exhibited high efficiency, as more than 85.6% TC (40 mg/L) instantaneous removal H2O2-based reaction. turnover number about 70 64 times higher that Fe-MOF FeNC-500. synergistic interaction among induced distribution around excellent performances. Moreover, interference resistance toward different anions humic acid. toxicity intermediate products decreased during degradation.

Metal nanozymes have offered attractive opportunities for biocatalysis and biomedicine. However, fabricating simultaneously possessing highly catalytic selectivity activity remains a great challenge due to the lack of three-dimensional (3D) architecture pocket in natural enzymes. Here, we integrate rhodium nanocluster (RhNC), reduced graphene oxide (rGO), protamine (PRTM, typical arginine-rich peptide) into composite facilely based on single peptide. Remarkably, PRTM-RhNC@rGO displays outstanding selectivity, activity, stability degradation uric acid.
