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.
