15 Ιουν 2024 · This study presents a thorough spectroscopic analysis of TiO 2 -Pt systems under LED irradiation, with a focus on elucidating the photodeposition process of Pt nanoparticles onto TiO 2...
1 Νοε 2018 · This methodology affords us to successful access to the novel plasmonic Pt/TiO 2 -HA (large Pt nanoparticles (NPs) supported on TiO 2 hierarchical nano-architecture (TiO 2 -HA))...
30 Σεπ 2023 · Pt forms a Schottky barrier at the interface of TiO 2, and this barrier improves the efficiency of photocatalytic reactions [6] compared to other dopants. Pt increases electron capture and therefore reduces the rate of electron–hole pair recombination.
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 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].
1 Ιαν 2020 · We report the remarkable production of H 2 and H 2 O 2 from pure water using porous brookite TiO 2 nanoflutes decorated with Pt nanoparticles through two-electron photocatalytic intermediate water splitting (PIWS).
