Abstract: A carbonylation-dehydration dual-functional catalyst precursor, a preparation method thereof, a carbonylation-dehydration dual-functional catalyst and use thereof are provided. The carbonylation-dehydration dual-functional catalyst precursor includes a modified silica-aluminum molecular sieve having an 8-member ring channel structure; a modified metal oxie loaded on the modified silica-aluminum molecular sieve having an 8-member ring channel structure by coupling, the coupling being performed using a silane coupling agent, wherein a modified component in the modified silica-aluminum molecular sieve having an 8-member ring channel structure includes at least one selected from the group consisting of copper oxide, zing oxide and iron oxide, and has a loading amount of 0.5-5 wt %, based on a metal mass of the modified component; and the modified metal oxie is prepared by modifying a composite metal oxide with an acid solution or an alkali solution, wherein the composite metal oxide is prepared based on a co-precipitation-calcination method.
