The invention provides a ferro-cobalt bimetallic load mordenite catalyst for catalyzing the nitrous oxide (N2O) decomposition and a preparation method. The catalyst can be used for decomposing most or all N2O in a pollution discharge system into N2 and O2 under the conditions that the space velocity is 30000h<-1>, the reaction temperature is 400 to 500 DEG C, the N2O concentration is 0.1 to 30 percent, and the H2O is 2 to 10 percent. In addition, the catalyst has high stability, and the activity of the catalyst is not decayed after 100h of the continuous nitric plant tail gas emission simulation. The catalyst has the advantages that the preparation process is simple, the cost is low, the catalyst is used for the catalytic N2O decomposition, the activity is high, and the stability is good. The technology has wide applicability, can be used for the N2O emission reduction process (such as processes of nitric acid production, adipate production and the like) of multiple industry sources and has wide application p
