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 ...
24 Μαΐ 2016 · The photocurrent of Pt-TiO 2 NPAs reaches to maximum at 10 cycles (i.e. 2.5 mA·cm −2 vs +0.5 V) and then decreases at 15 cycles, suggesting the electron sink effect is depended on the ...
18 Φεβ 2019 · Herein, novel synchronous illumination X-ray photoelectron spectroscopy combined with an angle-resolved technique (AR-SI-XPS) was employed for the first time to identify the interatomic electron transfer and interface bond changes on Pt/TiO 2 photocatalysts, which could promote overall water splitting while restraining undesirable hydrogen ...
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 Ιουν 2023 · The TEM-selected area electron diffraction (SAED) patterns of the prepared TiO 2 +Pt catalysts (inset in Fig. 2, with ab-initio simulations for anatase, Pt, and their mixture) correspond to anatase TiO 2 and the minor presence of Pt in all the examined TiO 2 +Pt samples.
1 ημέρα πριν · In hydrogen production through water splitting, two reactions are involved: Hydrogen Evolution Reaction (HER) and Oxygen Evolution Reaction (OER), both with efficiency issues. In previous works, our group demonstrated the possibility to enhance H2 production through HCOOH photocatalytic reforming on metal-Ti
