The Effect of Deposition Potential on the Electrodeposition of Platinum Nanoparticles for Ethanol Electrooxidation

open access: yesChemistry and Materials, 2022
Platinum (Pt) nanoparticles were successfully prepared using square wave pulse deposition technique by varying the upper potential. The X-ray energy dispersive spectrum pattern confirmed the formation of Pt nanoparticles on the fluorine-doped tin oxide ...

Mn ions' site and valence in PbTiO3 based on the native vacancy defects

open access: yesCondensed Matter Physics, 2021
Mn ions' doping site and valence were studied in PbTiO3 (PT) with the native vacancy defects by the first-principles calculations. Firstly, the native vacancy defects of Pb, O and Ti in PT were investigated and it was found that Pb vacancy is preferred ...

Synthesis of Pt(II)−Pt(II) and Pt/Pd(II)−Pt(0) Monoalkynylphosphine Bridging Complexes

open access: yesOrganometallics, 2002
The monoalkynylphosphine complexes cis-[Pt(C 6F 5) 2(PPh 2CCR)(tht)] (R = Ph 1a, Tol 1b, tBu 1e, tht = tetrahydrothiophene) have been prepared by bridge splitting [{Pt(C 6F 5) 2(-tht)} 2] or by displacement of only one tht ligand from cis- [Pt(C 6F 5) 2(tht) 2] with PPh 2CCR.

Initial stages of Pt growth on Ge(001) studied by scanning tunneling microscopy and density functional theory [PDF]

open access: yes, 2004
We have studied the initial stages of submonolayer Pt growth on the Ge(001). We have observed several stable and meta-stable adsorption configurations of Pt atoms at various temperatures. Calculations indicate relatively high binding energies of Pt atoms
