[Problem] To provide a method for preparing a highly active and highly durable catalyst in which the elution of catalytic metals is inhibited when carrying out liquid phase oxidation without using an alkali; and a method for manufacturing an oxide with high efficiency using the catalyst. The method for preparing the catalyst has the following steps 1, 2, and 3. Step 1: Preparing an aqueous dispersion of the catalyst in which Pt is deposited on active carbon Step 2: Preparing an aqueous solution that includes Bi in an ionic state Step 3: Adding the aqueous dispersion obtained in step 1 to the aqueous solution obtained in step 2 |
