PURPOSE: A bismuth phosphate-containing a multi-component-based metal oxide catalyst, a method for preparing the same, and a method for preparing 1,3-butadiene using the same are provided to improve the yield of the 1,3-butadiene by increasing the selectivity of the catalyst. CONSTITUTION: A method for preparing a bismuth phosphate-containing a multi-component-based metal oxide catalyst includes the following: The catalyst is represented by chemicl formula 1. A bismuth precursor, an iron precursor, and a nickel precursor are dissolved in an aqueous solution, and the dissolved aqueous solution is introduced into a molybdenum precursor dissolved aqueous solution to obtain a first solution. A phosphorus precursor is added into the first solution to obtain a second solution. The pH value of the second solution is adjusted to be in a range between 3.0 and 6.0. A stirring process and a coprecipitating process are implemented to obtain a coprecipitated solution. The coprecipitated solution is filtered to obtain a solid sample. The solid sample is dried at a temperature between 80 and 110 degrees Celsius in order to obtain a dried catalyst. The dried catalyst is thermally treated at a temperature between 400 and 600 degrees Celsius. |
