1. A noble metal-transition metal complex catalyst supported on a carbon-coated silica-alumina carrier, wherein
40 parts by weight to 95 parts by weight of alumina (Al2O3) and 5 parts by weight to 60 parts by weight of silica (SiO2) are included based on 100 parts by weight of the carbon-coated silica-alumina carrier; and
2 parts by weight to 20 parts by weight of the noble metal and the transition metal are included based on 100 parts by weight of the carbon-coated silica-alumina carrier,
wherein the noble metal includes one or more selected from the group consisting of palladium (Pd), rhodium (Rh), ruthenium (Ru), and platinum (Pt),
the transition metal includes one or more selected from the group consisting of tin (Sn), iron (Fe), rhenium (Re), and gallium (Ga), and
an amount of the transition metal is in a range of 1 part by weight to 10 parts by weight based on 100 parts by weight of the carbon-coated silica-alumina carrier.
