Transparent ZnO–SnO2 Photocatalytic Nanocoatings Prepared by the Polymer–Salt Method

Porous Ceramic ZnO Nanopowders: Features of Photoluminescence, Adsorption and Photocatalytic Properties

“…The photoluminescence (PL) method previously used in [11,33] was applied for the estimation of the material's ability to generate chemically-active singlet oxygen under light irradiation. The measurements of PL spectra in the near IR spectral range were performed using an SDH-IV spectrometer (SOLAR Laser Systems, Minsk, Republic of Belarus) with luminescence excitation by LED HPR40E (λ max = 405 nm; power density of light 0.35 W/cm 2 ).…”

“…Chicago Sky Blue (CSB) diazo dye (Sigma Aldrich Rus Ltd., Moscow, Russia) was used as the model organic contaminant for the estimation of adsorption and photocatalytic properties of prepared ZnO powders. This dye was used previously for the study of photocatalytic and adsorption properties of different materials [32,33]. Adsorption and photocatalytic properties of powders were studied in their suspensions, which were prepared by the addition of 0.01 g of ZnO to 3 mL of the aqueous solution of Chicago Sky Blue (CSB) dye (0.01 g/L).…”

“…The polymer-salt method is simple, cheap and is applied for the synthesis of different oxides nanoparticles (NPs) [11,15,[31][32][33][34]. Solutions containing soluble polymer and thermally decomposable metal salts are used as oxide NPs precursors in this method.…”
