Surfactant-Free Synthesis of Crystalline Mesoporous Metal Oxides by a Seeds/ NaCl-Mediated Growth Strategy.

ABSTRACT: Transitional metal oxides (TMOs) with ultra-high specific surface areas (SSAs), large pore volume, and tailored exposed facets appeal to significant interests in heterogeneous catalysis. Nevertheless, synthesizing the metal oxides with all the above features is challenging. Herein, the so-called seeds/NaCl-mediated growth method is successfully developed based on a bottom-up route. First, the (Brunauer-Emmett-Teller) BET SSAs of TMOs prepared with this method are significantly higher, where the BET SSAs of CeO₂ , SnO₂ , Nb₂ O₅ , Fe₃ O₄ , Mn₃ O₄ , Mg(OH)₂ , and ZrO₂ reached 187, 275, 518, 212, 147, 186, and 332 m²  g^-1 , respectively. Second, these TMOs exhibit
