Facile Synthesis of the Tridecameric Al13 Nanocluster

Treatment of aluminum nitrate with an organic nitroso-containing compound yields the “flat”, tridecameric nanocluster Al13(μ3-OH)6(μ2-OH)18(H2O)24(NO3)15 (Al13) in good yield on a preparative scale under ambient conditions.

Formation of Al13I-: Evidence for the Superhalogen

200442 · The calculated energy to remove the I atom from Al 13 I – is 2.46 eV. It is apparent that this cluster can emerge as a product of the acid-etching pathways described above. For example, the reaction of Al 14– with HI would require 1.80 eV to remove an Al atom from the cluster and 3.09 eV to break the H-I bond.

Mechanism of fluoride removal by AlCl3 and Al13: The role

2020115 · Obviously, Al 13 had better performance over wider pH ranges than AlCl 3 did, which was consistent with the conditions in high-fluoride water. Excessive addition of AlCl 3 also deteriorated fluoride removal, bringing about high residual aluminum concentrations (Fig. S2b) and sharp decreases in pH (Fig. S2c).
