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.
