Impact of LED radiation intensity on gold nanoparticles photodeposition on TiO₂ with physicochemical and photocatalytic characterization.

ABSTRACT: This study investigates the influence of LED radiation intensity on the photodeposition of gold nanoparticles onto TiO₂ substrates, examining their physicochemical properties and photocatalytic activities. Utilizing a range of radiation intensities and wavelengths, TiO₂-Au composites were synthesized and characterized through techniques such as X-ray diffraction (XRD), scanning electron microscopy (SEM) with energy dispersive X-ray (EDX), and X-ray photoelectron spectroscopy (XPS). The deposition process, markedly enhanced by shorter wavelengths and higher intensities, efficiently formed gold nanoparticles. This research distinctly highlights observable morphological changes in the nanoparticles; increased radiation intensity not only augmented the size but also alter
