摘要:

甲苯是一种来源广泛的芳香族化合污染物,对人体健康及环境都产生强烈的危害。锰氧化物具有形貌可控、晶体结构多样、价态可变等特点,被认为是最具有应用潜力的甲苯氧化催化剂。本文综述了近年来锰基催化剂催化氧化甲苯的研究进展,主要介绍了单一锰氧化物和复合锰氧化物,讨论了形貌、晶型结构、氧空位、金属-载体相互作用等因素对甲苯催化氧化性能的影响,并归纳了一部分甲苯催化氧化的反应机理。最后,提出开发简单的合成工艺以构建MnO x 纳米催化剂或Mn基复合纳米催化剂,研究实际的工业尾气影响催化剂行为的因素等是该领域未来的研究方向。

Abstract:

Toluene is an aromatic pollutant coming from a wide range of sources, which causes strong harm to human health and environment. Manganese oxide is considered as the most potential catalyst for oxidation of toluene due to its controllable morphology, diverse crystal structure and variable valence state. In this paper, the research progress of catalytic oxidation of toluene by manganese-based catalysts in recent years was reviewed, including single manganese oxide and composite manganese oxide. The effects of morphology, crystal structure, oxygen vacancy, metal-carrier interaction and other factors on the catalytic oxidation performance of toluene were discussed. The catalytic reaction mechanisms of toluene oxidation were also summarized. Finally, it is suggested that developing a simple synthesis process to construct MnO x or Mn-based composite nano-catalyst, and studying the actual factors affecting the catalyst behavior for industrial exhaust are the future research directions in this field.

Key words: toluene catalytic oxidation, manganese oxide, activity, oxygen species
