WebStable blue suspensions of 2 nm diameter iridium oxide (IrO x ·nH 2 O) nanoparticles were obtained by hydrolyzing IrCl 6 2-in base at 90 °C to produce [Ir(OH) 6] 2-and then treating with HNO 3 at 0 °C. UV-visible spectra show that acid condensation of [Ir(OH) 6] 2-results in quantitative conversion to stable, ligand-free IrO x ·nH 2 O nanoparticles, which have an … Web5,928 Likes, 61 Comments - IrohPosts 𥳐 (@irohposts) on Instagram: "Thoughts on this?
