Coupling of nanocrystal hexagonal array and two-dimensional metastable substrate boosts H2-production

open access: yesNature Communications, 2022
The construction of well-ordered nanoarrays, particularly invoking metastable material phases, remains a challenge. Here, authors prepared a well-ordered, rhodium nanoarray on two-dimensional, metastable rhodium oxide to enhance hydrogen evolution ...

Dry impregnation in fluidized bed: Drying and calcination effect on nanoparticles dispersion and location in a porous support [PDF]

open access: yes, 2008
The synthesis of metal nanoparticles dispersed inside the grains of a porous inorganic support was carried out by ‘‘dry impregnation’’ in a fluidized bed.

Synthesis of Solution-Phase Phosphoramidite and Phosphite Ligand Libraries and Their In Situ Screening in the Rhodium-Catalyzed Asymmetric Addition of Arylboronic Acids [PDF]

open access: yes, 2007
Herein, we report the automated parallel synthesis of solution-phase libraries of phosphoramidite ligands for the development of enantioselective catalysts.

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.

Catalytic coatings on steel for low-temperature propane prereforming to solid oxide fuel cell (SOFC) application [PDF]

open access: yes, 2009
Catalyst layers (4–20 lm) of rhodium (1 wt%) supported on alumina, titania, and ceria–zirconia (Ce0.5Zr0.5O2) were coated on stainless-steel corrugated sheets by dip-coating in very stable colloidal dispersions of nanoparticles in water.

Metallo-intercalators and metallo-insertors [PDF]

open access: yes, 2007
Since the elucidation of the structure of double helical DNA, the construction of small molecules that recognize and react at specific DNA sites has been an area of considerable interest.

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-

Asymmetric Hydrogenation in Water by a Rhodium Complex of Sulfonated 2,2'-Bis(diphenylphosphino)-1,1'-binaphthyl (binap) [PDF]

open access: yes, 1993
The synthesis of sulfonated 2,2′-bis(diphenylphosphino)-1,1′-binaphthyl (binap) is reported; a rhodium complex of this ligand is the first to perform asymmetric hydrogenation in neat water with optical yields as high as those obtained in nonaqueous ...

The reconstruction of Ni and Rh (001) surfaces upon Carbon, Nitrogen, or Oxygen adsorption

open access: yes, 1998
Nickel and Rhodium (001) surfaces display a similar - as from STM images - clock reconstruction when half a monolayer of C/Ni, N/Ni or O/Rh is adsorbed; no reconstruction is observed instead for O/Ni.
