Visible Light-Induced Photocatalyst with Au/TiO2 Nanocomposites Fabricated through Pulsed Laser-Induced Photolysis

Gold–titanium oxide nanocomposites (Au–TiO2 NCPs) were fabricated through pulsed laser-induced photolysis (PIPS) and verified to be usable for the visible light catalytic degradation of methylene blue (MB). The PIPS method can produce a sufficient amount NCPs quickly has potential commercialized. In contrast other studies, we clarified optical spectrum sources, including peak power, bandwidth, total intensity used photodegradation reactions discovered that efficiency produced Au–TiO2 in wavelength range 405 nm could reach 37% 30 min due charge transfer between Au TiO2. control experiment shows addition individual TiO2 nanoparticles (NPs) an MB solution no enhancement ability under illumination. further improved by increasing concentrations auric acid NPs precursor fabrication.
