Abstract	Carbon nanotubes (CNTs) [1], with their unique physicochemical properties, have attracted broad attention due to their potential applications [2]. A recent in situ study on the oxidation of different types of CNTs has revealed that the initiation temperature of CNT oxidation depends on the wall thickness of the CNTs [3]. Singleand double-wall CNTs can oxidize at lower temperatures and multi-wall CNTs can be stable in oxygen even at temperatures as high as 520 oC [3]. With the use of catalyst nanoparticles to facilitate the oxidation processes the initiation temperature and the degree of carbon oxidation can be drastically changed [4]. Understanding the behavior of catalyzed oxidation processes is critical to developing better catalysts for combustion of particulates including oxidation of soot particles [5]. We report here the in situ investigation of Ag catalyzed oxidation of multi-wall CNTs inside an aberration-corrected environmental TEM (AC-ETEM) with the goal of probing the nature of the catalyzed oxidation processes and thus developing better understanding of combustion catalysts.
