THE ACTIVE SITES AND PERFORMANCE OF Mn1Cex/HZSM-5 CATALYST FOR FORMALDEHYDE REMOVAL AT ROOM TEMPERATURE

  • 摘要: 装修等产生的室内甲醛严重影响人体健康,因此在室温下降解甲醛的需求日益迫切。目前,常温催化氧化法被视为最有前景的甲醛处理方法之一。沸石分子筛具有较大比表面积及较多吸附位点,以此为载体,以MnOx和CeOx为反应活性位点,通过共沉淀法成功合成了Mn1Cex/HZSM-5催化剂。该催化剂在常温下可降解96.86%的甲醛且具有良好的稳定性。此外,通过一系列的物理化学表征分析发现,Ce物种不仅能够显著提高催化剂中高价态锰的含量,还能带来更多的表面吸附羟基和吸附氧,进而提升催化剂的性能。鉴于其优异及稳定的性能、简便的合成方法,此高效除甲醛Mn1Cex/HZSM-5催化剂可为室温下除甲醛催化剂的合成提供新的参考。
