Dataset: Glass-forming ability and structural features of melt-quenched and gel-derived SiO2-TiO2 glasses
<p>Research data for Manuscript submission with title</p> <p><strong>Glass-forming ability and structural features of melt-quenched and gel-derived SiO<sub>2</sub>-TiO<sub>2</sub> glasses</strong></p> <p><strong>Abstract</strong></p> <p>SiO<sub>2</sub>-TiO<sub>2 </sub>glasses produced by melt-quenching or sol-gel spray-drying were compared to highlight their structural differences. Glass formation was possible by melt-quenching up to 10 mol% TiO<sub>2</sub>, while higher contents led to devitrification. Raman spectroscopy and solid-state <sup>17</sup>O and <sup>29</sup>Si MAS NMR confirmed the clear emergence of Ti-O-Si bonds and a tetrahedral oxygen coordination of Ti<sup>4+</sup> leading to full network connectivity, as also substantiated by the synthesis of TiO<sub>2</sub>-doped cristobalite. In gel-derived glasses, water content induced partial network depolymerization, thereby enhancing the solubility of TiO<sub>2</sub> in the hydrous silicate matrix. However, full dehydration during heating proved challenging due to the competing devitrification tendency: the glass-forming range in the anhydrous binary SiO<sub>2</sub>-TiO<sub>2</sub> system does not therefore appear to be significantly enlarged by the sol-gel synthesis route.</p>

Data from: Preparation of Pt and bamboo charcoal co-modified TiO2 for formaldehyde sensing at room temperature
<p>Anatase TiO<sub>2</sub> has evolved to be one of the most attractive materials for gas sensing due to its strong oxidation activity and excellent sensing properties. In this study, we prepared a Pt and bamboo charcoal co-modified nano-TiO<sub>2</sub> using one-pot hydrothermal process and applied it for detection of formaldehyde. The successful incorporation of precious metal Pt and bamboo charcoal onto TiO<sub>2</sub> was confirmed by SEM, TEM, EDS, XRD, and XPS. These modifiers significantly improved the response of TiO<sub>2</sub> to formaldehyde, e.g., the response signal increased by 4 times, while the response time decreased from 91.05 to 67.76 s. The sample with 0.5@Pt and 0.5@C bamboo charcoal performed the best. Our work showed the potential of using biomass-derived carbon to improve the detection of formaldehyde.</p>

Physico-chemical characterization of sterilized TiO2 D540 nanoparticles by XPS / HAXPES / SEM
<p>Here a dataset of XPS, HAXPES and SEM measurements for the physico-chemical characterization of sterilized nanoparticles is presented. The measurements are part of the H2020 project “NanoSolveIT”.</p> <p>TiO<sub>2</sub> D540 nanoparticles, which are TiO<sub>2 </sub>particles, with a diameter of about 540nm, were provided by Promethean Particles and treated differently by project partners from the University of Birmingham (EMR identifier in the project: ERM00000415, ERM00000457, ERM00000436).</p> <p>The particles were treated by different sterilization methods (autoclave or microwave) and BSA was or was not added as stabilizer. This finally leads to five different samples: pristine, autoclave, microwave, autoclave with BSA, microwave with BSA.</p> <p>Prior to the measurements, the samples were prepared from the solution as drop cast on Si wafers. First SEM and EDS measurements were performed, followed by XPS and HAXPES measurements on the same samples. Here at first survey spectra were recorded followed by high resolution spectra. For XPS / HAXPES several Si-wafers were mounted together on one platen. The platen was left in the intro chamber of the instrument for several hours before the measurement started.</p> <p>Equipment:</p> <p>SEM images were acquired with a <em>Supra 40 </em>(Zeiss) SEM equipped with a <em>Quantax 400 </em>(Bruker) SDD EDS spectrometer.</p> <p>For X-ray spectroscopy experiments, a combined XPS / HAXPES spectrometer (<em>Quantes </em>from ULVAC-PHI) was used, where XPS is measured at 1486.6 eV (monochromatic Al Kα source) and HAXPES at 5414.9 eV (monochromatic Cr Kα source). Here it is possible to perform the measurements at the exact same position.</p> <p>Data:</p> <p>For SEM, the data are given in .tif format. For XPS / HAXPES the raw data are given as .spe (PHI format) and .npl (VAMAS format) files. The measurement conditions are given in the data files.</p> <p>Naming of data:</p> <p>SEM: <em>sample_treatment (n)</em>, with n a consecutive number.</p> <p>XPS / HAXPES: For the .spe and for the corresponding .npl files <em>Pn.m.o.sample_treatment,</em> with Pn: platen-number, m: spectrum number (order of the measurements); o: point-number, of the position on the sample, sample_treatment with "m" for microwave and "a" for autoclave.</p> <p>The authors thank Sigrid Benemann, who performed the SEM measurements.</p>
