The invention discloses application of a carbon nanotube internally-deposited metal particle catalyst in reaction for synthesizing cinnamyl alcohol through selective catalytic hydrogenation of cinnamyl aldehyde. The catalyst is composed of a carbon nano tube, sulfur-nitrogen co-doped carbon quantum dots and metal nano particles, the carbon nano tube is a single-walled or multi-walled carbon tube with holes, the outer wall of the carbon nano tube is loaded with the carbon quantum dots, and metal nano particles are embedded in the inner wall of the carbon nano tube; the metal is one of palladium, platinum, gold, ruthenium, iridium, nickel and cobalt; and the size of the sulfur-nitrogen co-doped carbon quantum dots is not more than 10nm, the nitrogen content is 0.1-1.0wt%, and the sulfur content is 0.1-3.0wt%. When the catalyst is used for selective catalytic hydrogenation of cinnamyl aldehyde to synthesize cinnamyl alcohol, high conversion rate, high selectivity, high stability, high catalytic efficiency and lo
