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 · 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.
1 Νοε 2018 · Particularly, the Pt/TiO2-HA shows an excellent photocatalytic activity for overall water splitting rather than only for hydrogen evolution (HE), which is superior to those of the...
18 Φεβ 2019 · Photo-controlled bond changes on Pt/TiO 2 for promoting overall water splitting and restraining hydrogen–oxygen recombination †. Yajun Zhang,a Hongyan Hu,*a Xiaojuan Huang a and Yingpu Bi *a . Author affiliations. Abstract.
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 surfaces.
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.
24 Μαΐ 2016 · The presence of Pt deposits on TiO 2 is believed to retard the rapid charge-pair recombination by serving as an electron sink and facilitating interfacial electron transfer to dioxygen or...
