Metal nanoparticles (MNPs) are synthesized using various techniques on diverse substrates that significantly impact their properties. However, among the substrate materials investigated, major challenge is stability of MNPs due to poor adhesion substrate. Herein, it demonstrated how a newly developed H-glass can concurrently stabilize plasmonic gold nanoislands (GNIs) and offer multifunctional applications. The GNIs simple yet, robust thermal dewetting process. embedded with demonstrates versatility in its applications, such as i) acting room temperature chemiresistive gas sensor (70% response for NO

The aim of this study is to investigate new catalytic systems for the degradation a dye that has been classified as first-degree toxic pollutant. Advanced oxidation process such photocatalytic oxidation, ultrasonic Fenton, and Fenton-like constitute promising technology treatment wastewater containing organic compounds. Waste effluents from textile industries are major source water pollution. These wastewaters contain dyes, which have high toxicity low biodegradability. In study, Nile Blue (NB), an azo dye, was studied using (TiO2 silver-loaded TiO2 (Ag-TiO2) catalyst), Fenton (Fe(II)/H2O2), (Cu(II)/H2O2, V(IV)/H2O2) processes. It found NB increased with decreasing pH, rate also in presence TiO2/UV compared UV irradiation alone. addition, Ag loading on dramatically reduced time. different initial concentrations at pH values amplitudes. Concentrations Fe(II), Cu(II), V(IV) H2O2 ratio were investigated. Fe(II) ion more effective than Cu(II) ions NB.
