Oxidation Behavior of Non-Modified and Rhodium- or Palladium-Modified Aluminide Coatings Deposited on CMSX-4 Superalloy

open access: yesMetals, 2018
Rhodium-modified as well as palladium-modified and non-modified aluminide coatings on CMSX-4 Ni-based superalloy were oxidized in air atmosphere at 1100 °C. Uncoated substrate of CMSX-4 superalloy was also oxidized.

Promoting effect of Rh on the activity and stability of Pt-based methane combustion catalyst in microreactors

open access: yesCatalysis Communications, 2021
For the combustion of methane, a partial replacement of platinum by rhodium leads to a significantly improved light-off behavior of the corresponding mixed Pt-Rh/γ-Al2O3 catalysts compared to a catalyst containing only Pt supported on γ-Al2O3. For all Pt-
