27 Δεκ 2021 · Here, we have developed model Pt/TiO 2 catalysts based on the deposition of colloidal Pt nanoparticles and studied their atomic and electronic structures before and after a postdeposition treatment that induces catalytic activity using aberration-corrected scanning transmission electron microscopy, electron energy loss spectroscopy, and first ...
23 Ιουλ 2019 · X-ray diffraction (XRD) patterns for samples of nanoparticles having different sizes and shapes can look different, and careful analysis of the XRD data can provide useful information and also help correlate microscopic observations with the bulk sample.
This Calculator can determine crystallite or grain size by using XRD graph. Peak position and FWHM values are needed. Peak Position (2θ) FWHM (2θ) X-Ray Wavelength.
1 Ιουν 2023 · The TEM-selected area electron diffraction (SAED) patterns of the prepared TiO 2 +Pt catalysts (inset in Fig. 2, with ab-initio simulations for anatase, Pt, and their mixture) correspond to anatase TiO 2 and the minor presence of Pt in all the examined TiO 2 +Pt samples.
23 Ιουν 2021 · The step-by-step method in the calculation based on the XRD data is presented, which can help especially students and first-time users in understanding XRD results.
15 Ιουν 2024 · This study presents a thorough spectroscopic analysis of TiO2-Pt systems under LED irradiation, with a focus on elucidating the photodeposition process of Pt nanoparticles onto TiO2...
1 Νοε 2018 · This methodology affords us to successful access to the novel plasmonic Pt/TiO2-HA (large Pt nanoparticles (NPs) supported on TiO2 hierarchical nano-architecture (TiO2-HA)) photocatalysts...
