Abstract: A preparation method and use of a novel pure inorganic solid silicon-based sulfonic acid and/or phosphoric acid catalytic material are disclosed. The surface hydroxyl-rich metasilicic acid is used as the raw material, and by using a sulfonating reagent and/or phosphoric acid, the sulfonic acid group and/or the phosphoric acid group are bonded to the inorganic silicon material by chemical bonding to obtain a pure inorganic solid silicon-based sulfonic acid and/or phosphoric acid catalytic material. The catalytic material can be widely used in many acid-catalyzed organic reactions such as isomerization, esterification, alkylation, hydroamination of olefins, condensation, nitration, etherification, multi-component reactions and oxidation reactions.
