Application

Rhodium(III) chloride hydrate (RhCl3. xH2O) can be used as a metal precursor in the synthesis of:
  • Rhodium-cobalt (Rh-Co) (a bimetallic catalyst) supported on silica for Fischer−Tropsch (FT) synthesis.
  • Rhodium (III) catalyst, N-2-(2,3,4,5 tetramethylcyclopentadienyl)benzyl-(l)-norephedrine rhodium(III) chloride for asymmetric ketone reduction.
  • Rh@CTF (covalent triazine frameworks) catalyst for the hydroformylation of 1-octene.

The shapes of noble metal nanoparticles directly impact their properties and applications, including in catalysis and plasmonics, and it is therefore important to understand how multiple distinct morphologies can be controllably synthesized. Solution routes offer powerful capabilities for shape-controlled nanoparticle
