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 Ιουν 2023 · The aim of the present study was to investigate in detail how the optical, electronic and catalytic properties of TiO 2 +Pt catalysts with 1 wt% Pt loading depend on the textural and morphological properties of the TiO 2 support.
The experimental XRD pattern agrees with the JCPDS card no. 21-1272 (anatase TiO2) and the XRD pattern of TiO2 nanoparticles other literature [8]. The 2θ at peak 25.4° confirms the TiO2 anatase structure [9]. Strong diffraction peaks at 25° and 48° indicating TiO2 in the anatase phase [10].
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...
1 Νοε 2018 · This methodology affords us to successful access to the novel plasmonic Pt/TiO2-HA (large Pt nanoparticles (NPs) supported on TiO2 hierarchical nano-architecture (TiO2-HA)) photocatalysts...
1 Ιουλ 2022 · In the first set of experiments, we deposited Pt single atoms on the different polymorphs of the TiO 2 nanoparticles (i.e., anatase, rutile, and P25) by exposure to a 0.005 m m H 2 PtCl 6 solution for 24 h (details are given in the Experimental Section).
15 Απρ 2022 · This systematic review is centered on the synthesis, physio-chemical properties and applications of Pt-based TiO 2 catalysts with a special attention to energy and environmental applications. Finally; limitations, challenges and future prospects of Pt-modified TiO 2 photocatlytic systems are also briefly addressed.
