General description

Iridium(III) acetylacetonate is a thermallystable organic precursor widely used in the chemical vapor deposition process.It has relatively high saturated vapor pressure and low sublimationenthalpy.

Application

Iridium(III)acetylacetonate can be used as a precursor in the preparation of:
  • Iridium coatings by metallo-organic chemical vapor deposition (MOCVD).
  • Iridium oxide nanoclusters (IrOx). ZrOCoII−IrOx can be used as a catalyst in carbon dioxide reduction.
  • MgF2–MgO supported Iridium catalyst for CO oxidation.(3)

Fuel cells are expected to be one of the most promising alternatives to the increasingly scarce fossil fuels, and Pt is the most commonly used catalyst for anodic and cathodic electrochemical reactions. To realize large-scale commercialization, it is most urgent

An all-inorganic polynuclear unit consisting of an oxo-bridged binuclear ZrOCo(II) group coupled to an iridium oxide nanocluster (IrO(x)) was assembled on an SBA-15 silica mesopore surface. A photodeposition method was developed that affords coupling of the IrO(x) water oxidation catalyst

For the first time, shape-tunable Pt-Ir alloy nanocatalysts including both single-crystalline (nano-octahedra (NOs), nano-truncated octahedra (NTOs), nanocubes (NCs)) and polycrystalline (nanocluster flowers (NCFs), nanowires (NWs), nano-short-chains (NSCs), and nano-octahedral stars (NOSs)) ones were synthesized with a facile one-pot solvothermal method

Nanoframe electrocatalysts have attracted great interest due to their inherently high active surface area per a given mass. Although recent progress has enabled the preparation of single nanoframe structures with a variety of morphologies, more complex nanoframe structures such as
