The invention discloses a catalyst for catalyzing the dehydrogenation of alcohols, a preparation method and application thereof. The catalyst is a catalyst with a copper-based hydrotalcite-ZrO 2 composite carrier structure, and its chemical formula is: Cu x -Cry - Mz /Mg (6-x) Al (2-z) -Zr w ; wherein, x=1.8-2.5, y=0.01-0.04, z=0.05-0.1, w=0.05-0.15, and M is a rare earth element. The catalyst for catalyzing the dehydrogenation of alcohols is used in the selective dehydrogenation reaction of alcohols. The invention can show good catalytic activity, selectivity, carbon deposition resistance and stability under relatively mild reaction conditions, solve the problems of easy deactivation of similar catalysts and short catalytic life cycle, and the raw materials are economical and easy to obtain, and the preparation process It is simple and has broad application prospects. |
