Abstract

Abstract:

Soot particles released from diesel exhaust are one of the main sources of urban smog, which seriously pollute the environment and endanger human health. Therefore, it is of great significance to reduce and eliminate soot particles. In this paper, a series of manganese oxide catalysts were successfully prepared by self-propagating combustion technique using potassium permanganate acid and citric acid monohydrate as raw materials. The catalysts were characterized by means of X-ray diffraction (XRD), scanning electron microscope (SEM), N₂ adsorption-desorption measurements, H₂ temperature-programmed reduction (H₂-TPR), O₂ temperature-programmed oxidation (O₂-TPD) and X-ray photoelectron spectroscopy (XPS). The catalytic performance of the as-prepared catalysts for soot combustion was also investigated. The results showed that all the as-prepared manganese oxide catalysts had good catalytic activity for soot combustion. When the mole ratio of potassium permanganate and citric acid was 12∶1 and the calcination temperature was 450℃, the obtained catalyst had the lowest reduction peak temperature, the largest specific surface area and pore diameter and chemisorbed oxygen and Mn⁴⁺ content. Thus, it exhibited the best catalytic performance for soot combustion and its T₁₀, T₅₀ and T₉₀ temperatures were 284℃, 327℃ and 360℃ respectively for soot combustion.

Key words: self-propagating combustion method, manganese oxides, catalyst, catalysis, soot particles

摘要：

柴油机尾气中的炭烟颗粒是城市雾霾的主要来源之一，严重污染环境和危害人体的健康。因此，降低和消除柴油车尾气中的炭烟颗粒具有重要的意义。本文以高锰酸钾和一水柠檬酸为原料，通过自蔓延燃烧法成功制备了一系列锰氧化物催化剂。采用X射线衍射（XRD）、扫描电子显微镜（SEM）、N₂吸附-脱附、H₂程序升温还原（H₂-TPR）、O₂程序升温氧化（O₂-TPD）和X射线光电子能谱（XPS）等手段对催化剂进行了表征，并考察了该系列催化剂催化炭烟颗粒燃烧的活性。结果表明，制备的锰氧化物催化剂均具有良好的催化燃烧炭烟活性。当高锰酸钾与一水柠檬酸的摩尔比为12∶1、煅烧温度为450℃时，制备的催化剂具有较低的还原峰温度，较大的比表面积和孔径以及化学吸附氧和Mn⁴⁺含量，从而表现出最佳催化燃烧炭烟颗粒的性能，其催化燃烧炭烟温度T₁₀、T₅₀和T₉₀分别为284℃、327℃和360℃。
