Platinum Inhibits Low‐Temperature Dry Lean Methane Combustion through Palladium Reduction in Pd−Pt/Al2O3: An In Situ X‐ray Absorption Study
Palladium–platinum bimetallic catalysts supported on alumina with palladium/platinum molar ratios ranging from 0.25 to 4 are studied in dry lean methane combustion in the temperature range of 200 to 500 °C. Platinum addition ...
Water shifts PdO-catalyzed lean methane combustion to Pt-catalyzed rich combustion in Pd-Pt catalysts: In situ X-ray absorption spectroscopy
The addition of platinum to palladium is known to provide bimetallic catalysts that are relatively active in lean methane combustion in the presence of water at temperatures below 773 K, which is of practical interest for ...
Supported Bimetallic AuPd Clusters Using Activated Au25 Clusters
Bimetallic AuPd nanoparticles on alumina supports were prepared using Au25(SR)18 precursors activated by mild calcination or LiBH4 treatment, followed by selective deposition of Pd via ascorbic acid reduction. Comparison ...
Following the Reactivity of Au25(SC8H9)18 - Clusters With Pd2+ and Ag+ Ions Using in Situ X-ray Absorption Spectroscopy: A Tale of Two Metals
(American Chemical Society, 2015)
This work examines the reaction between Au25(SC8H9)18– clusters with palladium acetate (Pd2+) and silver nitrate (Ag+) using UV–vis, transmission electron microscopy (TEM), extended X-ray absorption spectroscopy (EXAFS), ...
