The present invention provides a method for producing an oxide catalyst for producing acrylic acid. The present invention includes the steps of preparing a catalyst precursor from a solution containing a molybdenum salt, a vanadium salt, a tellurium salt, and a niobium salt, and then drying and calcining the precursor. The invention is characterized by removing impurities from the prepared catalyst by ball milling in the presence of a polar solvent. Therefore, according to the method of the present invention, an oxidation catalyst for producing acrylsan having a very high catalytic activity can be prepared. |
