The M41S family mesoporous materials are recognized promising due to their suitable pore size for accommodating high molecular weight petroleum fractions[1].However, these mesostructured materials have much lower acidity and hydrothermal stability, which can be attributed to the amorphous nature of the pore wall.Many research efforts have been focused on how to improve the acidity and stability of the mesoporous materials, and several important factors are associated with the enhanced hydrothermal stability for mesoporous materials[2-3].
