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 ...
The XRD analysis of the prepared sample of TiO 2 nanoparticles was done using a Bruker make diffractometer, Cu-Kα X-rays of wavelength (λ)=1.5406 Å and data was taken for the 2 θ range of 10° to 70° with a step of 0.1972°.
X-ray diffraction (XRD) studies revealed that TiO2 NCs exhibit tetragonal crystal configuration with anatase-type symmetry with \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage ...
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.
Download scientific diagram | XRD patterns of Pt nanocrystals with different sizes. 111, 200 and 220 reflections were fitted using Gaussians. The fitting results are shown in red.
23 Ιουλ 2019 · Powder XRD provides useful information about structure, phase, composition, shape, size, crystallinity, and other important features of nanoscale materials, although unambiguous sample characterization almost always requires complementary experimental and/or computational methods.
3 Ιουλ 2019 · In this work, we present state-of-the-art first-principles calculations on the electronic and optical properties of TiO 2 by utilizing the DFT and DFPT to describe ground and excited state properties of TiO 2.
