Enhanced photocatalytic and electrochemical properties of green synthesized strontium doped titanium dioxide nanoparticles for dye removal and supercapacitor applications

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: March 26, 2025

The development of multifunctional nanomaterials for environmental remediation and energy storage is critical sustainable technologies. In this study, we synthesized strontium-doped titanium dioxide (Sr-TiO2) nanoparticles (NPs) via a green method investigated their structural, optical, electrochemical properties to enhance photocatalytic supercapacitive performance. Characterization results confirmed successful Sr incorporation into the TiO2 lattice. X-ray diffraction (XRD) analysis revealed slight shift in peak positions, indicating lattice distortion due doping. Scanning electron microscopy (SEM) showed uniform, well-dispersed nanoparticles, while energy-dispersive (EDX) spectra elemental composition. UV-visible spectroscopy (UV-Vis) demonstrated redshift absorption, reducing bandgap enhancing visible-light absorption. Fourier transform infrared (FTIR) identified characteristic functional groups, Brunauer–Emmett–Teller (BET) indicated increased surface area, favoring activity. performance Sr-TiO2 NPs was assessed through Methylene Orange (MO) Congo Red (Con-R) degradation under visible light at different pH levels. Under optimized conditions, achieved 94.48% MO removal 100 min 97.89% Con-R 70 min, following pseudo-first-order kinetics, demonstrating efficiency as visible-light-driven photocatalysts wastewater treatment. Electrochemical studies, including cyclic voltammetry (CV), charge-discharge tests, impedance (EIS), improved charge lower transfer resistance compared bare TiO2. exhibited enhanced specific capacitance good stability, underscoring potential high-performance electrode materials supercapacitors. These findings highlight approach by leveraging Sr-doped dual-functional applications.

Preparation of Functionalized Ethylene–Vinyl-Alcohol Nanofibrous Membrane Filter for Rapid and Cyclic Removing of Organic Dye from Aqueous Solution

Polymers, Journal Year: 2024, Volume and Issue: 16(16), P. 2328 - 2328

Published: Aug. 17, 2024

A functionalized ethylene-vinyl-alcohol (EVOH) nanofibrous membrane (NFM) was fabricated via co-electrospinning H4SiW12O40 (SiW12) and EVOH first, then grafting citric acid (CCA) on the electrospun SiW12@EVOH NFM. Characterization with FT-IR, EDX, XPS confirmed that CCA introduced to surface of NFM Keggin structure SiW12 maintained well in composite fibers. Due a number carboxyl groups by CCA, as-prepared SiW12@EVOH-CCA can form high hydrogen bonds CR, thus be used selectively absorb congo red (CR) aqueous solutions. More importantly, CR enriched rapidly degraded photocatalysis. acted as photocatalyst, hydroxyl an electron donor accelerate photodegradation rate CR. Meanwhile, regenerated exhibited relatively stable adsorption capacity five cycles filtration-regeneration. The bifunctional filter showed potential for use thorough purification dye wastewater.
