The invention discloses a manganese oxide formaldehyde degradation material and a preparation method and a catalyst thereof. The preparation method comprises the following steps: dissolving permanganate and starch in deionized water, stirring to obtain a precursor solution, reacting the precursor solution to obtain a precipitate, centrifugally cleaning, drying the precipitate to obtain an intermediate product, roasting the intermediate product to obtain MnO, and aging MnO in air to obtain the manganese oxide formaldehyde degradation material, the preparation process is simple and convenient, and the particle size distribution of the material is uniform. 本发明公开了一种锰氧化物甲醛降解材料及其制备方法和催化剂，将高锰酸盐、淀粉溶解在去离子水搅拌得到前驱体溶液；将前驱体溶液反应制得沉淀物；将沉淀物经离心清洗并烘干后得到中间产物；将中间产物焙烧得到MnO；将MnO在空气中老化后得到锰氧化物甲醛降解材料，制备工艺简便，材料颗粒尺寸分布均匀。
