The textile industry is one of the main industries that benefited from industrial revolution. Therefore, discharging dyes textile, paper, plastic, and rubber inevitable. This colored wastewater prevents sunlight penetration highly affects water sources. Cationic such as Rhodamine 6G (R6G) Methylene Blue (MB) obstruct plant growth, most these are nonbiodegradable. Thus, cationic observed to be more toxic than anionic reactive dyes. It a great challenge mankind detect remove aquatic ecosystem. Surface-enhanced Raman spectroscopy (SERS) an emerging cost-effective technique for detection any analyte at trace levels. Further, it very important design sensitive SERS substrate in lower concentrations. Owing high cost coinage metal substrates, semiconductor-based substrates have gained attention recently. Though pure semiconductors poor activity, incorporating graphene derivatives can further improve their surface optical properties make them active substrates. In order address this, we attempted synthesize reduced oxide/silver/zirconia (rGO-Ag-ZrO2) hybrid thin film nanocomposite using facile liquid/liquid interface method first time. synergistic effect rGO-Ag-ZrO2 efficient R6G until 100 pM multifunctional versatile application substrate, reusability by photodegradation antibiotic drug, was also explored

The development of systems capable efficiently eliminating organic dyes from wastewater is crucial for the environment. In this context, TiO2-based photocatalytic are particular interest. However, eco-friendly and single-step methods fabrication such remains a challenge to their practical use. Here, we demonstrate approach catalytic system composed TiO2 nanocoating created on surface bulk titanium plate by exposure nanosecond laser. conditions affect relief phase composition nanocoating, as revealed combination scanning electron microscopy (SEM), contact profilometry, Raman, High-resolution X-ray photoelectron spectroscopy (HR XPS), grazing incidence diffraction (GIXRD) methods. Using GIXRD method, establish that nanocoatings consist mixture anatase rutile grains with sizes 22.7–24.4 29.8–32.2 nm, respectively. HR XPS analysis demonstrates changes in number pulses per spot modify content 40.6 70.4%. samples higher exhibit up 6.3 times activity, which confirmed methylene blue degradation when exposed UV light can be related synergistic effect anatase–rutile heterojunction. reusability supported repeated experiments. activity obtained improved Au nanoparticles deposited magnetron sputtering. proposed lays foundation application laser-assisted technologies systems.
