Abstract: A copper nanocatalyst, a method for preparing the copper nanocatalyst, and an application of the copper nanocatalyst in the synthesis of acetate or ammonia are provided. The copper nanocatalyst includes a substrate and an active agent loaded on the substrate. The method includes: preparing a cleaning agent by using an ethanol and a deionized; immersing the active agent in the cleaning agent, ultrasonically cleaning for 5-10 min at a frequency of 4×104 Hz-8×104 Hz, and drying for later use; mixing the cleaned active agent and a conductive binder according to a mass ratio of 1:19-9:1 of the active agent to the conductive binder, adding the ethanol, and fully stirring and dispersing to obtain a slurry; coating the slurry on a surface of the carbon paper, and drying the carbon paper by blowing through nitrogen flow to obtain the catalyst.
