Abstract

At the present time, hybrid nanostructures attract significant attention among researchers because such materials allow combining advantages of different materials. For instance, the ability of metal nanoparticles to localize electromagnetic energy can be combined with low losses in the visible range of high-index nanoparticles. In this work, we demonstrate the method of creation of hybrid Au/TiO₂spherical nanoparticles using nanosecond pulsed laser ablation in deionized water. A titanium foil with a sprayed gold film of various thicknesses was used as an initial sample. The effect of the thickness of the gold film on the morphology of the obtained hybrid structures was demonstrated via SEM, and the elemental composition of the created nanoparticles was studied using EDX. The size distribution of the obtained nanoparticles was studied using DLS. We believe the obtained results create the basis for the development of affordable and efficient photocatalysts operating in the visible wavelength range.
