| Preparation: |
method previously reported by Henrist and coworkers (2003) and Lu and coworkers (2004); With
18.2 MΩ·cm Milli-Q water (Millipore), a 2.0 M MgCl2 solution (99.99% Alfa Aesar dry ampoules under Ar gas) and a solution containing 2.0 M NH4OH (Sigma–Aldrich, 25 wt.% solution) were prepeared; the MgCl2 was added dropwise to the NH4OH solution at a rate of approximately 2.5 mL min-1 using a graduated buret while keeping the latter solution vigorously stirred at a constant temperature of 45 ± 3 °C; after brucite precipitated, the sealed reaction vessel was set aside to cool at room temperature for 3 days; thoroughly washing of the soluble NH4Cl byproduct from the precipitate with Milli-Q water; precipitate was dried on a Corning PC-420D hot plate at 135 °C for 1 h. |
