Аннотация:
SBA-16-type mesoporous silica materials have been synthesized within 6h under weak acidic media by adding small amount of phosphomolybdic acid and inorganic salts. The reaction products have still maintained a well-ordered body-centered cubic (Im3m) mesostructure even after treated with 100 °C water for 120 h. High hydrothermal stability might be attributed to the higher degree of polymerization and condensation of silanol groups, originated from the synergistic effect of rapid nucleation with the aid of HPMo and salt effect during the crystallization process.
