Extremely small supported rhodium clusters were prepared from rhodium complexes on the surfaces of solids with contrasting electron-donor properties. The samples were characterized by infrared and extended X-ray absorption fine structure spectroscopies to determine the changes occurring in the rhodium species resulting from treatments in hydrogen. Rhodium cluster formation occurred in the presence of H2, and the first steps are controlled by the electron-donor properties of the support--which… 
Isostructural Zeolite-Supported Rhodium and Iridium Complexes: Tuning Catalytic Activity and Selectivity by Ligand Modification
A family of isostructural, essentially molecular complexes of rhodium and of iridium anchored to HY zeolite was synthesized from M(C2H4)2(acac) and M(CO)2(acac) (M = Rh, Ir; acac is acetylacetonate),
Tracking Rh Atoms in Zeolite HY: First Steps of Metal Cluster Formation and Influence of Metal Nuclearity on Catalysis of Ethylene Hydrogenation and Ethylene Dimerization.
The initial steps of rhodium cluster formation from zeolite-supported mononuclear Rh(C2H4)2 complexes in H2 at 373 K and 1 bar were investigated by infrared and extended X-ray absorption fine
Molecular Rhodium Complexes Supported on the Metal-Oxide-Like Nodes of Metal Organic Frameworks and on Zeolite HY: Catalysts for Ethylene Hydrogenation and Dimerization.
The data demonstrate a correlation between the catalytic activity and selectivity and the electron-donor tendency of the supported rhodium (as measured by the frequencies of CO ligands bonded as probes to the Rh(I) centers), which is itself a measure of theelectrolysis tendencies of the support.
Prospects of Heterogeneous Hydroformylation with Supported Single Atom Catalysts.
Keeping the balance between stability and activity appears to be the main challenge for oxide supported Rh hydroformylation catalysts, where it is found that rhodium carbonyl hydride complexes on flat oxide surfaces such as CeO2(111) have catalytic activities comparable to those of molecular complexes.
Molecular metal catalysts on supports: organometallic chemistry meets surface science.
The data provide examples resolving the roles of the catalyst design variables and place the catalysis science on a firm foundation of organometallic chemistry linked with surface science.
Ligand Stabilized Ni1 Catalyst for Efficient CO Oxidation.
D density functional theory calculation and molecular dynamics simulation are used to investigate the role of reactants and ligands on the reactivity and stability of graphitic carbon nitride supported Ni1 for CO oxidation and find out that supported bare Ni1 atoms are only metastable on the surface and tend to diffuse into the interlayer of g-C3 N4.
In situ formation of mononuclear complexes by reaction-induced atomic dispersion of supported noble metal nanoparticles
A general method with CO and CH3I to disperse the metal nanoparticles of Ru, Rh, Pd, Ag, Ir and Pt completely into single atoms with loading up to 5 wt%.
Computational investigation on the catalytic activity of Rh6 and Rh4Ru2 clusters towards methanol activation
Catalysis of molecular activation of small molecules through scission of strong chemical bonds is one of the major challenges faced by chemists. More specifically, activation of the strong C–H and

The results demonstrate not only new chemistry of the supported single-site catalysts but also their complexity and the value of complementary techniques used in concert to unravel the chemistry.


Surface-mediated synthesis of dimeric rhodium catalysts on MgO: tracking changes in the nuclearity and ligand environment of the catalytically active sites by X-ray absorption and infrared spectroscopies.
This work presents a novel synthetic route to generate rhodium dimers on the surface of MgO by a stoichiometrically simple surface-mediated reaction involving [Rh(C(2)H(4))(2)] species and H(2).

This is the first simple and nearly uniform supported mononuclear rhodium-olefin complex, and it appears to be a close analogue of molecular catalysts for olefin hydrogenation in solution.
A site-isolated rhodium-diethylene complex supported on highly dealuminated Y zeolite: synthesis and characterization.
The sharpness of the nu(CO) bands in the IR spectrum gives evidence of a nearly uniform supported Rh( CO)2 complex and, by inference, the near uniformity of the mononuclear rhodium complex with ethylene ligands from which it was formed.
