Abstract: Laser patterning of sol–gel-derived TiO2 coatings offers a promising route for fabricating TiO2-based devices. Conventional approaches require high-power CO2 lasers, whereas herein is demonstrated an alternative method using a low-cost, blue laser (λ = 445 nm, 1250 mW) to pattern TiO2 layers derived from a visible-light-absorbing titanium salicylate sol. Grid-shaped TiO2 patterns (~250 μm line, 500 μm pitch) were fabricated on indium tin oxide (ITO)-coated glass substrates via dip-coating, laser patterning, selective solvent removal, and annealing at 450 °C. Photocatalytic performance was enhanced through Ag photodeposition from a 5 mM Ag+ aqueous electrolyte under UV doses of 5, 10, and 20 J cm−2. Structural and compositional analysis (XRD, SEM-EDS, AFM, UV–Vis, Raman) confirmed the formation of crystalline anatase TiO2 and Ag incorporation proportional to the dose. Methylene blue (MB) photooxidation experiments revealed that Ag-functionalized samples showed up to 20% higher degradation efficiency and improved photocatalytic stability across eight consecutive MB oxidation cycles. Additional photoelectrochemical measurements confirmed the formation of a TiO2/Ag Schottky junction, while surface-enhanced Raman scattering (SERS) signals observed on Ag/TiO2 grids enabled the detection of MB adsorbates.
