AB  - Spherical core-shell Ag/ZnO nanocomposites were synthesised by ultrasonic spray pyrolysis (USP) method from zinc nitrate hexahydrate, Zn(NO3)2·6H2O (ZN) and silver nitrate, AgNO3 (SN) precursors. Varying solution concentrations and equipment installations (either single − or two-step USP) allowing simultaneous and consecutive precipitation of Ag and ZnO were examined regarding their effect on final particle microstructure and photocatalytic properties. Morphological analyses revealed pure Ag/ZnO core-shell structure where ZnO secondary submicron sized particles formed by primary crystals with the size of 5–20 nm. Depending on the solution concentrations and USP installations, various distributions of Ag in the final microstructure was revealed. Photocatalytic analyses (all samples reached >45% MB degradation) confirm the all Ag/ZnO USP systems viability for environmental applications. The best result (93% of methylene blue (MB) elimination) is obtained for the sample with the maximum available surface, which strongly depends on particle morphology, size, and dispersion. Moreover, all samples synthesised by single step co-precipitation revealed higher dye elimination concerning ones with two steps precipitation due to the favoured distribution of silver nanoparticles in their microstructure and higher specific surface area. Moreover, samples with a uniform and homogeneous Ag distribution exhibited silver-induced enhancement of photocatalytic performance. © 2017 Elsevier B.V.

AB  - Synthesis of ZnO:Ag core-shell nanoparticles were performed by ultrasonic spray pyrolysis (USP) from the corresponding nitrate solutions. Varying relative concentrations of Ag and ZnO precursors and two different equipment installation, allowing either common (single-step) or separate precipitation (two-steps) of Ag and ZnO, were examined in terms of their effect on final microstructure and photocatalytic properties using X-ray powder diffraction (XRPD), scanning and transmission electron microscopy (SEM, TEM, HRTEM), UV-Vis spectroscopy and photocatalytic tests. Formation of phase-pure ZnO:Ag core- shell like particles where ZnO secondary submicron sized particles formed by primary crystals with the size of 5-20 nm were confirmed by TEM analyses. Structural analyses revealed variations in silver distribution and morphology within ZnO core depending on experimental conditions. Samples with fine and uniform silver distribution on ZnO surface display a strong silver-induced enhancement of photocatalytic performance and exhibits a significantly improved photocatalytic activity in the degradation of methyl blue (MB) than that of other noble metal free ZnO systems. Photocatalytic analyses (all samples reached > 45% MB degradation) confirm the all synthesized ZnO:Ag USP systems viability for environmental applications. The best result (93% of dye elimination) is obtained for sample exhibiting maximum available surface, which strongly depends on particle morphology, size and distribution. Moreover, all samples synthesized by single-step USP revealed higher dye elimination with respect to ones with two- steps USP due to favored distribution of silver in microstructure.

In these systems, polyvinylpyrrolidone (PVP) is used as surfactant for controlling particle morphology, size and dispersion. The obtained materials are characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HR-TEM), UV–vis diffuse reflectance spectroscopy (DRS), N2 gas adsorption–desorption (BET) and Raman spectroscopy (RS). By XRD results, all major peaks are indexed to the hexagonal wurtzite-type structure of the ZnO and samples with noble metal, extra diffraction peaks are detected which correspond to the face-centered-cubic (fcc) structure of the metallic Ag. Depending on used precursor, different morphologies have been obtained. Mainly, ZnO prims-like rods – NRs (with 0.8 ⩽ aspect ratio ⩾ 3.4) – have been observed. Quasi-spherical particles of metallic Ag (with diameters between 558 ± 111 μm and 22 ± 1 nm) have been detected on the ZnO surface. Photocatalytic results (all samples studied >30% MB degradation) verify the important effect of surfactant and the viability of synthesized Ag/ZnO micro/nanocomposites for environmental applications.

AB  - Micro and nanostructured brucite (Mg(OH2)) particles synthesized by hydrothermal method from solutions with high content of hydrazine (0.14 M) and nitrate (0.24 g) were compared with samples obtained from low hydrazine content (0.0002 M) and nitrate (0.12 g). The samples were heated at 180 °C for 4 h, 6 h and 12 h. XRD, TEM-HRTEM, SAED and image analysis techniques were used for the morphological and structural characterization. The effect of electron beam irradiation on the brucite dehydration was observed in atomic resolution images at 300 kV. Hexagonal crystals show differences in crystallinity, strains and kinetic of reaction. High hydrazine/nitrate samples have slightly larger crystals with better crystallinity, showing a strong preferential orientation. Rietveld refinements show how unit cell parameters are bigger in samples obtained with higher hydrazine/nitrate content, confirming also the preferential orientation along the 0 0 0 1 plane. Differences in the dehydration process show the rapid formation of a porous surface, the amorphised cortex or the presence of highly oriented strains in samples prepared from higher hydrazine/nitrate content. Conversely, crystals slightly smaller with randomly scattered defect surfaces showing the Mg(OH)2/MgO interphase in samples prepared with low hydrazine/nitrate content. Significant differences in the kinetic of reaction indicate how the dehydration process is faster in samples prepared with high hydrazine/nitrate content.

AB  - Here, we report on the ZnO nanoparticles processing employing low-temperature (500 °C) ultrasonic spray pyrolysis (USP) method, using different Zn nitrate precursor solution concentrations (0.01, 0.1 and 1.0 M). Particle structural, morphological and luminescence characteristics were studied based on X-ray powder diffractometry, Fourier transform infrared spectroscopy, transmission electron microscopy (TEM/HRTEM), thermal analysis, UV–Vis diffuse reflectance spectra and photoluminescence measurements (PL). The generated so-called secondary particles have a hexagonal ZnO wurtzite-type crystalline structure with preferred orientation of (101) plane and quasi-spherical in shape. It was shown that such particle structural and morphological features are independent on the precursor solution concentrations used. All the PL spectra illustrate a strong green-yellow typical emission band exhibiting the corresponding redshift and variation of direct band gap from 3.22 to 3.12 eV with the increase in precursor concentration. The thermal analysis confirmed high thermal nanoparticles stability. The results proved that USP method successfully produces ZnO nanoparticles using neither dispersing agents nor post-heating treatments at high temperature, which allows rapid, continuous, single-step preparation, demonstrating a high potential for industrial applications.

AB  - Noble metal/ZnO nanoparticles were synthesized by a solvothermal method. The influence of reaction time, noble metal presence or kind of noble metal (Ag or Pt) was evaluated. The prepared samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), UV–vis diffuse reflectance spectroscopy (DRS) and BET surface area analysis. Hexagonal wurtzite and fcc were obtained for crystalline structures for ZnO and Ag/Pt, respectively. No characteristic phases which correspond to crystalline impurities were detected. It was displayed that ZnO nanoparticles presented nanowire morphology (NWs), while the metallic silver or platinum were found taking on quasi-spherical nanoparticles morphology (NPs), which appeared well dispersed onto ZnO NWs surface. Regarding particle sizes, ZnO aspect ratios were 2.5–13.3, Ag and Pt diameters were 17.3–24.3 nm and around ≈6.3 nm, respectively. The photocatalytic behavior of the synthesized systems was studied as well by the removing reaction of methylene blue (MB) in water solution. It was verified that the increase of the photocatalytic activity was due to the noble metal presence, exhibiting higher effect of silver than platinum. Photocatalytic results (all samples reached >70% MB elimination) demonstrated the viability of the noble metal/ZnO nanocomposites synthesized by solvothermal method for usage in environmental applications.
