Electronic spectroscopy of predissociative states of platinum oxide cation

چکیده
The photodissociation spectrum of jet-cooled PtOþ is reported over the range of 25 000 to 30 000 cm . Excited state vibrational progressions are identified for P 1=2 R3=2 and P5=2 R3=2 transitions with several vibrational peaks rotationally resolved. Additional peaks not assigned to a vibrational series also exhibit rotational structure. Transitions arising from the R3=2 ground state show a spectroscopic onset of 25 520 cm , giving an upper limit to the bond strength of D0(Pt þ–O) 6 305 kJ mol . A hot band is observed at 25 317 cm 1 and rotational analysis predicts it as arising from a low-lying X 1⁄4 7=2 state, probably D7=2. 2003 Elsevier B.V. All rights reserved.

In this work, the electrocatalytic oxidation of ethanol was studied in acidic media at the wholly electrosynthesized nanocomposites: platinum and its alloys (copper and nickel) anoparticles/reduced graphene oxide on the carbon-ceramic electrode (Pt/rGO/CCE, Pt-Cu/rGO/CCE, and Pt-Ni/rGO/CCE electrocatalysts). The electrosynthesized nanocomposites were characterized by scan...
متن کاملIntroducing Pt/ZnO as a new non carbon substrate electro catalyst for oxygen reduction reaction at low temperature acidic fuel cells
Gas diffusion electrode was used for providing better conditions in fuel cell systems for oxygen reduction reaction (ORR). Because the slow kinetics of the oxygen reduction reaction at the proton exchange membrane fuel cell cathode restricts fuel cell efficiency. To this end, researchers have used platinum-coated carbon. In the present study, due to the reduction of carbon corrosion, Zinc oxide...

Porous platinum thin films were prepared by thermal decomposition at temperatures from 25 to 675 °C of platinum oxide films deposited by a pulsed reactive sputtering technique. The samples’ chemistry and structure were investigated by x-ray diffraction (XRD), x-ray photoelectron spectroscopy (XPS), and x-ray absorption near edge structure (XANES), showing that the decomposition of the oxide beg...
