General description
Rh(CO)₂(acac) appears as a yellow to orange crystalline solid. It is soluble in various organic solvents such as benzene, toluene, and acetone, which makes it convenient for both solution-based synthesis and vapor-phase processing techniques. It is commonly used as a precursor for the deposition of rhodium-containing thin films and nanomaterials. Its ability to decompose cleanly under controlled conditions makes it suitable for processes like chemical vapor deposition (CVD) and atomic layer deposition (ALD), enabling the fabrication of conductive coatings, catalytic layers, and electronic materials. Additionally, it serves as a molecular precursor for synthesizing rhodium nanoparticles, which are employed in applications such as fuel cell catalysts, hydrogen evolution reactions, and nanoelectronics.
Application
Employed in in situ formation of a fluorous-soluble hydroformylation catalyst of interest in molecular engineering.
Rh(CO)₂(acac) can be used:
- As a precursor for the synthesis of rhodium nanosheets which are used in catalysis which are utilized as a support for bimetallic PtRh nanoparticles, significantly enhancing their catalytic activity in oxidation reactions.
- As a catalyst for the selective hydrogenation of dioctyl phthalate (DOP) to produce the environmentally friendly plasticizer di(2-ethylhexyl)hexahydrophthalate (DEHHP).
- As a precursor for the synthesis of single-atom rhodium catalysts which are used in electrocatalytic reactions, such as the hydrogen evolution reaction (HER).
- As a molecular precursor for synthesis of rhodium nanoclusters on oxide surfaces, such as Al₂O₃/Ni₃Al(111) via physical vapor deposition (PVD) (5)
Features and Benefits
- 98% purity minimizes impurities, enhancing catalytic activity in hydrogenation and carbonylation reactions for higher reaction rates and improved selectivity.
- The absence of impurities in the product enhances electrochemical properties, resulting in more efficient and reliable performance in electrochemical cells and sensors.

Triply vibrationally enhanced four-wave mixing spectroscopy is employed to observe vibrational coherence transfer between the asymmetric and symmetric CO-stretching modes of rhodium(I) dicarbonyl acetylacetonate (RDC). Coherence transfer is a nonradiative transition of a coherent superposition of quantum states to a
