Supported catalyst and preparation method of 7-octenal

Abstract

A supported catalyst comprises: a carrier including a composite material of magnesium oxide and aluminum oxide, and a first active metal and a second active metal supported on the carrier, wherein the carrier comprises 200 to 1000 parts by weight, based on a total weight of 100 parts by weight of the first active metal and the second active metal. The first active metal is copper, and the second active metal is chromium, zinc, or cobalt.
