Abstract

Poly( N -vinylpyrrolidone (PVP)-capped platinum and rhodium nanoparticles (7−12 nm) have been studied with UV−vis, FTIR, and Raman spectroscopy. The absorption bands in the region of 190−900 nm are shown to be sensitive to the electronic structure of surface Rh and Pt atoms as well as to the aggregation of the nanoparticles. In-situ FTIR-DRIFT spectroscopy of the thermal decay of PVP-stabilized Rh and Pt nanoparticles in H 2 and O 2 atmospheres in temperatures ranging from 30 to 350 °C reveals the decomposition of PVP above 200 °C; PVP transforms into a “polyamide−polyene”-like material that is, in turn, converted into a thin layer of amorphous carbon above 300 °C. Adsorbed carbon monoxide was used as a probing molecule to monitor changes of the electronic structure of surface Rh and Pt atoms and accessible surface area. The behavior of surface Rh and Pt atoms with ligated CO and amide groups of pyrrolidones resembles that of surface coordination compounds.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
