“…On the other hand, photogenerated holes of the Bi 2 S 3 valence band transfer to the AgCl nanoparticles on the surface and react with chloride ions to create Cl • radicals which enable them to oxidize the AB92 chemical structure strongly and degrade it. As the previous researchers repeatedly highlighted this in their reports, the enhancement of the electron-hole recombination efficiency toward reaching an improved photocatalaytic performance owes the prominent bridge-like role of Ag nanoparticles between the Bi 2 S 3 and AgCl counterparts on the matrix surface of the plasmonic photocatalysts [36]. The presence of Ag crystalline phase in our work was already confirmed by XRD analysis results.…”

“…The aqueous solution of this organic wastewater was poured into a double-jacketed Pyrex reactor surrounded by circulating water at 25 °C which keeps the temperature of the photodegradation reactions constant (scheme 1). The reactor is placed on a magnetic stirrer and 10 cm below the illumination source, OSRAM lamp 125 W (the emission spectrum of the lamp is provided at: [36]). The whole collection is located in a well aluminum foil-covered wood box to concentrate the photons on the reaction medium.…”

A visible-light-active plasmonic photocatalyst was prepared from bismuth sulfide particles modified with Ag-AgCl nanoparticles. The structure of the photocatalyst was analyzed using powder X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), elemental mapping, nitrogen adsorption-desorption isotherms (BET-BJH), and diffuse reflectance spectroscopy (DRS). To evaluate the photocatalytic performance, Acid Blue 92 (AB92) azo dye was degraded in an aqueous solution under visible light illumination. It was found that 0.025 g of the photocatalyst was able to remove over 98% of the AB92 solution at a concentration of 15 ppm and pH 7.5, in accordance with pseudo-first-order kinetics. Superoxide anion radicals (O2-˙) are key components of the photodegradation pathway. Furthermore, the antibacterial activity of the material was investigated against E. coli and S. aureus under irradiation and dark conditions. Transmission electron microscopy (TEM) images of the treated cells showed that the plasmonic photocatalyst destroyed the gram-positive and gram-negative bacterial cell wall structures within two hours of treatment. It is possible that this was caused by efficient generation of destructive superoxide anion radicals on the surface of Ag-AgCl/Bi2S3 particles.

“…Tetrazolium salts (TSs) are an important class of compounds with versatile uses in chemistry, biology, and physics [ 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 ]. Two different TSs were used in this study: 2,3,5-triphenyltetrazol-2-ium;chloride (tetrazolium red, TTC) and 2-[4-[4-(3,5-diphenyltetrazol-2-ium-2-yl)phenyl]phenyl]-3,5-diphenyltetrazol-2-ium;dichloride (neotetrazolium chloride, NTC) ( Figure 1 ).…”

Two new vanadium (V) complexes involving 6-hexyl-4-(2-thiazolylazo)resorcinol (HTAR) and tetrazolium cation were studied. The following commercially available tetrazolium salts were used as the cation source: tetrazolium red (2,3,5-triphenyltetrazol-2-ium;chloride, TTC) and neotetrazolium chloride (2-[4-[4-(3,5-diphenyltetrazol-2-ium-2-yl)phenyl]phenyl]-3,5-diphenyltetrazol-2-ium;dichloride, NTC). The cations (abbreviated as TT+ and NTC+) impart high hydrophobicity to the ternary complexes, allowing vanadium to be easily extracted and preconcentrated in one step. The complexes have different stoichiometry. The V(V)–HTAR–TTC complex dimerizes in the organic phase (chloroform) and can be represented by the formula [(TT+)[VO2(HTAR)]]2. The other complex is monomeric (NTC+)[VO2(HTAR)]. The cation has a +1 charge because one of the two chloride ions remains undissociated: NTC+ = (NT2+Cl−)+. The ground-state equilibrium geometries of the constituent cations and final complexes were optimized at the B3LYP and HF levels of theory. The dimer [(TT+)[VO2(HTAR)]]2 is more suitable for practical applications due to its better extraction characteristics and wider pH interval of formation and extraction. It was used for cheap and reliable extraction–spectrophotometric determination of V(V) traces in real samples. The absorption maximum, molar absorptivity coefficient, limit of detection, and linear working range were 549 nm, 5.2 × 104 L mol−1 cm−1, 4.6 ng mL−1, and 0.015–2.0 μg mL−1, respectively.
