| 中文摘要: |
| 本文采用共沉淀以及煅烧法制备了Co3-xMnxO4固溶体纳米花催化剂, Mn元素的引入有效提高了催化剂的表面氧空位浓度, 提高了其甲醛催化氧化性能. 对催化剂的结构、形貌、元素价态和氧空位等进行了表征和研究. 与Co3O4相比, Co2MnO4表现出明显增强的甲醛催化氧化性能, 在60 min内甲醛的氧化分解率达到71%. |
| 英文摘要: |
| This article uses co-precipitation and calcination methods to prepare Co3-xMnxO4 solid solution nanoflower catalysts. The introduction of Mn element effectively increases the surface oxygen vacancy concentration of the catalyst and improves its formaldehyde catalytic oxidation performance. The structure, morphology, elemental valence states, and oxygen vacancies of the catalyst are characterized and studied. Compared with Co3O4, Co2MnO4 exhibits significantly higher catalytic oxidation performance for formaldehyde, with a decomposition rate of 71% within 60 min. |
