Fund Project:

The liquid crystalline phase micell formed from cetyltrimethylammonium hydro-xide was used as template with simultaneous introduction of a synergistic extractant TOPO-D₂EPHA into it. A mesoporous molecular sieve embedded with synergistic extractant MCM-TP was obtained. It is formed through the self-assembly process between the hydrophilic groups of the micell and organic silicate anions. The results from TEM, XRD, and ²⁹Si-MASNMR showed that the sieve had a similar hexagonal arrangement of uniform mesopores as that of MCM-41, but an improved hydrothermal stability with saturation adsorption of 0.015 mmol[Pd]/g.
