Profex is a program for Rietveld refinement of powder X-ray diffraction (XRD) data based on the refinement kernel BGMN. It can be used for phase identification, phase quantification, structure refinement, and provides a large number of convenience features.
Download scientific diagram | XRD patterns for rutile, anatase, and mixed TiO2 phases. The JCPDS #75-1537 for TiO2 is shown as a reference.
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 surfaces.
1 Ιουν 2023 · Synthesized TiO2 +Pt solids can be used as photo, thermal and photothermal catalysts. •. The nature of the TiO2 support affects the interaction between Pt and TiO2. •. The Schottky barrier enables the separation of charge carriers in TiO2+Pt catalysts. •. Visible-light illumination of TiO2 +Pt lowers the deNOx process ignition temperature. •.
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°.
