In‐Situ Coating of SBA‐15 with MgO: Direct Synthesis of Mesoporous Solid Bases from Strong Acidic Systems

Abstract

Basic mesoporous materials (see Figure) are synthesized directly from a strong acidic solution for the first time. This is achieved by in‐situ coating of SBA‐15 with basic MgO by adding acetate salt into the initial mixture of raw materials for synthesis. The synthesis and modification is performed in a one‐step procedure. The magnesium acetate not only acts as the precursor of MgO, but also leads to a better order in the mesostructure.
