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 ...
5 Ιαν 2023 · Self-Enhanced Catalytic Activity of Pt/TiO 2 via Electronic Metal–Support Interaction. Pt nanoclusters confined in ordered mesoporous TiO 2 facilitate the generation of interfacial active sites (Ti 3+ -O v -Pt δ+) during the reaction, enhancing the cyclic catalytic activity.

XRD pattern of TiO 2 nanoparticles The X-ray diffraction pattern of the synthesized Titania nanoparticles is shown in Fig.1 and the peak details are in Table.
Download scientific diagram | XRD patterns for rutile, anatase, and mixed TiO2 phases. The JCPDS #75-1537 for TiO2 is shown as a reference.
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.
