Comparative Study of Pt/Pd and Pt–Rh/Pt Thermocouples

International Journal of Thermophysics, 2010
The Pt/Pd thermocouple has demonstrated superior thermoelectric drift and homogeneity performance over conventional Pt–Rh/Pt thermocouples. Here, we present a systematic comparison of the drift and homogeneity performance of Pt/Pd and Type R thermocouples by ageing the thermocouples at 1350 °C for a total of 500 h and measuring the performance at ...

NO Chemisorption on Pt(111), Rh/Pt(111), and Pd/Pt(111)

The Journal of Physical Chemistry B, 2005
The chemisorption of NO on clean Pt(111), Rh/Pt(111) alloy, and Pd/Pt(111) alloy surfaces has been studied by first principles density functional theory (DFT) computations. It was found that the surface compositions of the surface alloys have very different effects on the adsorption of NO on Rh/Pt(111) versus that on Pd/Pt(111).

Origin of Anomalous Pt–Pt Distances in the Pt/Alumina Catalytic System

ChemPhysChem, 2004
The Pt/g-alumina system is representative of many common heterogeneous catalysts, which consist of transition metals dispersed on a high surface-area support. For example, catalytic reduction and oxidation of automotive pollutants is accomplished with platinum (Pt) or rhodium (Rh) dispersed on a galumina surface.

[Pt]

Angewandte Chemie (International ed. in English)
The intermediacy of CO/NO substitution in the condensation of [Pt(19)(CO)(22)](4-) into [Pt(38)(CO)(44)](2-) (structure shown) has been demonstrated. Two high-nuclearity carbonyl metal clusters, including one with an unprecedented nitrosyl ligand, have been synthesized and structurally characterized.

Coordination of Atomic Co-Pt Coupling Species at Carbon Defects as Active Sites for Oxygen Reduction Reaction.

Journal of the American Chemical Society, 2018
Platinum (Pt) is the state-of-the-art catalyst for oxygen reduction reaction (ORR), but its high cost and scarcity limit its large-scale use. However, if the usage of Pt reduces to a sufficiently low level, this critical barrier may be overcome ...
