The invention provides a preparation method of a carbon nanotube loaded nickel-molybdenum alloy catalyst, which comprises the following steps: A) treating a carbon nanotube by using a Hummers method to obtain a treated carbon nanotube; b) mixing the treated carbon nanotubes, polyvinylpyrrolidone, nickel salt, molybdate, alcohol and water, then dropwise adding ammonia water, reacting for 10-30 minutes, and then carrying out hydrothermal reaction; and C) drying the product of the hydrothermal reaction, and calcining at a high temperature in a hydrogen-containing atmosphere to obtain the carbon nanotube loaded nickel-molybdenum alloy catalyst. The invention also provides a carbon nanotube loaded nickel-molybdenum alloy catalyst and application thereof. 本发明提供了一种碳纳米管负载镍钼合金催化剂的制备方法，包括以下步骤：A)使用Hummers法处理碳纳米管，得到处理后的碳纳米管；B)将处理后的碳纳米管、聚乙烯吡咯烷酮、镍盐、钼酸盐、醇和水混合，然后滴加氨水，反应10～30min之后，进行水热反应；C)将水热反应的产物干燥后，在含氢气气氛下进行高温煅烧，得到碳纳米管负载镍钼合金催化剂。本发明还提供了一种碳纳米管负载镍钼合金催化剂及应用。
