The invention relates to a method for producing 1,3-propanediol with glycerol as material by way of gas phase hydrogenolysis of glycerol, which includes the following step that: under the existence of metal-acid bifunctional catalyst, the glycerol receives gas phase hydrogenolysis, so that the 1,3-propanediol is prepared; and the invention also relates to the application of the metal-acid bifunctional catalyst in the reaction for preparing the 1,3-propanediol by way of gas phase hydrogenolysis of glycerol. The metal-acid bifunctional catalyst contains the following components loaded on carrier: (a) solid acidic active component, (b) metal component (one of copper, nickel or cobalt) with hydrogenation activity, and (c) optionally added metal addition agent component (one or more of iron, zinc, tin, manganese and chromium). The method can directly obtain the 1,3-propanediol by way of hydrogenolysis, as well as 1,2-propanediol. The method has the advantages of mild reaction conditions, simple technique and continuous operation.
