The present invention provides a method for producing a microporous body and a denitration catalyst capable of maintaining high catalytic activity for a long time at a low temperature advantageous in terms of energy. A mixing step of forming an alkaline inorganic material mixed solution comprising at least one crystallization regulator selected from ammonium ions, phosphonium ions, and amines, a silicon dioxide component, and a noble metal catalyst element component. And performing a solid-liquid separation step of separating the fine particles precipitated in the mixed solution from the inorganic material mixed solution after the mixing step, and heating and crystallizing the solid component separated by solid-liquid separation. I do. [Selection] Figure 4 |
