• Halloysite
• Manganese oxides
• In-situ deposition
• Low-temperature SCR

Halloysite (HNTs) was firstly adopted as a carrier to develop manganese based SCR catalysts. Supporting of manganese oxides (MnO). on halloysite was carried out via a simple in-situ reaction of Mn(AC)(2) and KMnO4 on the surface of halloysite. The obtained MnOx/HNTs catalyst was estimated for selected reduction of NO by NH3. It was found that the SCR activity of the catalyst is perfectly high with a nearly 100% NO conversion at temperatures from 60 to 250 degrees C. Results showed that the adoption of Halloysite as carrier and the in-situ preparation method jointly play key function for the performance of the catalyst.
