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 dye-sensitization of these Pt@TiO2 core-shell structures allows for a high photocatalytic activity for the generation of hydrogen from proton reduction under visible-light irradiation.
1 Δεκ 2023 · Pt clusters encapsulated by sub-15 nm TiO 2 promotes electrons migration. •. Intimate attachment is realized by electrostatic assembling method. •. It is an possible example of the high value-added exploitation for converter slag. •. A type-II heterojunction TiO 2 -Pt/FeHAp achieves a H 2 generation rate of 3026 μmol·g −1 ·h −1. Abstract.
Based on energy dispersive X-ray spectroscopy (EDS) analysis, the amount of Pt nanoparticle loading was estimated to be 3.8 wt% and X-ray diffraction (XRD) measurement indicated that the ...
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.
1 Ιουν 2023 · The low intensity or absence of Pt diffraction peaks in the acquired XRD diffractograms of TiO 2 +Pt catalysts (Fig. 2) can be ascribed to the low amount of deposited Pt, weak crystallinity, non-spherical shape and small size of the Pt particles, and/or the high dispersion of Pt particles over the TiO 2 supports [39], [40], [41], [42].
According to X-ray diffraction (XRD) analysis, TiO 2 NPs-N 2 contained uniformly integrated Au nanoparticles with an average crystallite size of about 26.8 nm. The XRD patterns showed that the...
