Manganese oxide has been recognized as one of the most promising gaseous heterogeneous catalysts due to its low cost, environmental friendliness, and high catalytic oxidation performance. Mn-based oxides can be classified into four types: (1) single manganese oxide (MnOx), (2) supported manganese oxide (MnOx/support), (3) composite manganese oxides (MnOx-X), and (4) special crystalline manganese oxides (S-MnOx). These Mn-based oxides have been widely used as catalysts for the elimination of gaseous pollutants. This review aims to describe the environmental applications of these manganese oxides and provide perspectives. It gives detailed descriptions of environmental applications of the selective catalytic reduction of NOx with NH, the catalytic combustion of volatile organic compounds, Hg oxidation and adsorption, and soot oxidation, in addition to some other environmental applications. Furthermore, this review mainly focuses on the effects of structure, morphology, and modified elements and on the role of catalyst supports in gaseous heterogeneous catalytic reactions. Finally, future research directions for developing manganese oxide catalysts are proposed.

“…Manganese oxides, including MnO, MnO 2 , Mn 2 O 3 , and Mn 3 O 4 , are of considerable importance in many applications, such as ion-exchange, molecular adsorption, catalysis, electrochemical reaction, batteries, and magnetism, due to their structural flexibility with novel chemical and physical properties. − Among these manganese oxides, Mn 2 O 3 is well-known as a cheap and environment-friendly catalyst for removing carbon monoxide and nitrogen oxide from waste gas, − and is also used to produce soft magnetic materials such as manganese zinc ferrite . Much attention has been paid to nanostructures due to the fact that the drastic increase in the ratio of surface area to volume causes the appearance of unique physical and chemical properties. − The nanostructured materials have potential technical applications because of their distinctive optical, mechanical, electrical, acoustic, and magnetic properties. − Mn 2 O 3 nanocrystals are expected to exhibit better properties in the following respects: a larger surface-to-volume ratio and an improved capacity to absorb more oxygen for oxidation of carbon monoxide and nitrogen. − Therefore, the investigations of Mn 2 O 3 nanocrystals have become the new focus in the field of materials science and engineering technology.…”

For hard tissue replacement, an implant with a multifunctional surface, which combines long term anticorrosion potential, osteogenesis and antibacterial properties is one of the most ideal products people strive for. In this work, stable Mn-containing titania coatings on titanium were obtained by introducing a strong electrolyte and strong oxidant, potassium permanganate (KMnO 4 ), into a conventional micro-arc oxidation (MAO) electrolyte solution. The MAO-synthesized Mn-containing titania coating showed a compacted surface, which results in excellent anticorrosion capacity and provides a stable Mn delivery platform that can sustainedly release Mn ions at a desirably slow rate for more than 6 weeks. The subsequent releasing of Mn ions improves the osteogenic activity and antibacterial ability of the titania coating. Thus, we have combined osteogenesis and antibacterial properties in an Mn-containing titania coating, which provides insight into the design of better biomedical implant surfaces in the future.
