Stable to surfactant removal by calcination , Ti‐TMS1 is the first hexagonally packed, mesoporous transition metal oxide. The synthesis of this new material was achieved by a modified sol–gel technique from titanium alkoxides and phosphate surfactants. The large internal surface area, narrow and controllable pore size, thermal stability, and variable oxidation states of the metal give this new material great potential as a catalyst and sorbent.
