Abstract In this study, novel polyaniline-coated perovskite nanocomposites (PANI@CoTiO 3 and PANI@NiTiO ) were synthesized using an in situ oxidative polymerization method evaluated for the photocatalytic degradation of Rhodamine B (RhB) a persistent organic pollutant. The displayed significantly enhanced efficiency compared to pure perovskites. 1%wt achieved impressive 94% RhB under visible light after 180 min, while 1wt.% PANI@CoTiO3 reached 87% UV same duration. X-ray diffraction (XRD) confirmed that crystalline structures CoTiO NiTiO remained intact post-polymerization. At time, Fourier transform infrared spectroscopy (FTIR) verified successful deposition PANI through characteristic functional group vibrations. Diffuse reflectance (DRS) revealed reduced band gaps 2.63 eV 2.46 PANI@CoTiO , enhancing absorption across ranges. Scanning electron microscopy (SEM) energy dispersive (EDS) analysis demonstrated uniform distribution PANI, ensuring consistent surface activity efficient charge transfer. test pseudo-first-order mechanism. study elucidates mechanism intermediate identification via HPLC-MS analysis, highlighting N-de-ethylation, aromatic ring cleavage eventual mineralization into CO 2 H O as critical pathways. Furthermore, 1wt.%PANI@NiTiO nanocomposite excellent stability recyclability, maintaining its over four consecutive cycles with minimal change. These findings highlight potential PANI@XTiO sustainable wastewater treatment, addressing diverse environmental challenges by tailoring photocatalysts specific sources.

WO₃ as an Electron Exchange Matrix: A Novel and Efficient Treatment Method for Nitro Compounds

ACS Omega, Год журнала: 2025, Номер unknown

Опубликована: Март 13, 2025

To minimize the use of chemicals that have traditionally been needed to treat toxic organic compounds, a WO3 electron exchange matrix (EEMWO3), which requires fewer chemical solvents in line with green chemistry engineering principles, was developed for waste degradation. The EEMWO3 tested its ability remove 4-nitrophenol and 2-nitrophenol, were chosen as models common oxidizing compounds. nitrophenol added an initial amount 7.19 × 10-5 mol, is larger concentration than reported cause health problems. conversion values ∼(10-50)%, depending on type substrate used. Ca. 10% units observed be reduced by BH4 - W(V), value orders magnitude better previously EEM. results indicate structure surface area are important parameters degradation process. monoclinic hydrotungstite (WO2(OH)2·H2O) reactive species. same also affected recyclability process, three cycles possible commercial WO3. tungsten oxide functioned active EEM without entrapped redox species skeleton, indicating one does not worry about number can matrix. It concluded efficient treatment method toxic, compounds it greener whose conventional methods.

Bismuth-based photocatalytic materials have been widely used in the field of photocatalysis recent years due to their unique layered structure. However, single bismuth-based are greatly limited performance poor response visible light and easy recombination photogenerated charges. At present, constructing semiconductor heterojunctions is an effective modification method that improves quantum efficiency by promoting separation electrons holes. In this study, successful preparation
