In this study, the commercial TiO2 nanopowder and micropowder of anatase phase and rutile phase have been characterized by x-ray diffraction (XRD) and transmission electron microscopy (TEM). XRD patterns of nano-TiO2 in rutile and anatase phases exhibit broad peaks whereas both phases of micro-TiO2 demonstrate very sharp peaks.

27 Νοε 2022 · The present work aimed at the development of Pt-TiO2/SiO2 materials applied to the degradation of a pharmaceutical pollutant in a fixed-bed microreactor in continuous mode. First, a wide investigation of the optimal platinum content in TiO2/SiO2 was carried out based on extensive characterization through XRD, DRS, SEM, TEM, and XPS techniques.
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°.
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 ...
1 Ιουλ 2022 · Abstract. For more than 20 years, Pt/TiO 2 represents the benchmark photocatalyst/co-catalyst platform for photocatalytic hydrogen (H 2) generation. Here, single atom (SA) Pt is decorated on different polymorphs of TiO 2 (anatase, rutile, and the mixed phase of P25) using a simple immersion anchoring approach.
1 Ιουν 2023 · Abstract. TiO 2+Pt plasmonic solids with 1 wt% Pt and different TiO2 supports (anatase nanoparticles (TNP), polycrystalline nanorods (a-TNR) and single-crystal anatase nanorods (TNR)) were synthesized using the wet impregnation technique and tested as photo, thermal and photothermal catalysts in gas-solid and gas-liquid-solid reactions.
