The invention belongs to the field of catalysts, and particularly relates to a copper-silicon DMO hydrogenation catalyst and a preparation method thereof. The invention aims to solve the problem of low catalytic efficiency caused by low copper loading capacity in the existing silicon-loaded copper catalyst. The ligand-protected copper silicate catalyst with a large cage structure is synthesized by adopting a controllable hydrolysis method of organic silanol and an aryl complex of copper, the method is simple and efficient, the copper content of the obtained catalyst is greater than 37% (the copper content of a common copper-based catalyst is 25% at most), the catalytic efficiency is high, the reactant conversion rate is up to 100%, and the catalyst is suitable for industrial production. The problem of low copper loading capacity in the silicon-loaded copper-containing catalyst is well solved, and the silicon-loaded copper-containing catalyst can be used in efficient DMO hydrogenation catalytic reaction. 本发明属于
