中文摘要:
      锰氧化物具有活性高、毒性低、资源丰富、合成方法多样等优点,常作为许多催化反应的催化剂或载体材料。该文综述了近年来锰氧化物催化剂的研究进展,主要介绍了单一锰氧化物、掺杂改性的锰氧化物以及锰氧化物复合材料在甲醛催化氧化反应中的催化性能;讨论了形貌、晶型结构以及其他因素对催化性能的影响;并归纳了一部分甲醛催化氧化的反应机理;最后指出要发展高效、经济、环保的锰氧化物催化剂,通过构建更多的缺陷,添加助剂,掺杂改性等方法,增加活性面和活性位的数量,来提高锰氧化物的催化性能是未来的主要研究方向。
英文摘要:
      Manganese oxides are often used as catalysts or support materials for many catalytic reactions due to its many advantages, such as high activity, low toxicity, abundant resources and various synthesis methods. Herein,the recent progresses of manganese oxides catalysts for catalytic oxidation of HCHO have been summarized, the catalytic properties of single manganese oxides, doped manganese oxides and manganese oxide composites in the catalytic oxidation of formaldehyde were introduced, and the main factors that influence the catalytic properties have been reviewed in terms of morphology, structure and crystalline phase, as well as other factors. Besides, the reaction mechanisms for catalytic oxidation of for-maldehyde over some manganese oxides catalysts have also been summarized. It is indicated that future research of manganese oxides catalysts with high efficiency, economy and environmentally benign on ox-idation of HCHO should be improved the catalytic performance by increasing the number of active sites, constructing more defects, adding additives and doping modification.
