Atmospheric aerosol particles, defined as a suspension of a liquid or solid particle in a gas [1]... more Atmospheric aerosol particles, defined as a suspension of a liquid or solid particle in a gas [1], are considered as air pollutants due to their impact on the environment, climate, and public health [2]. Among these pollutants, Diesel Particulate Matter (DPM) causes a significant impact on the global warming and health problems. DPM trapping by means of filtration and periodic filter regeneration by DPM combustion have been investigated [3]. Due to the highly complex nature, ambiguity, and unpredictability of the soot structure, Diesel Particulate Filter (DPF) optimization is a challenging task [4]. Previous studies have focused on some structural characterization of diesel soot formed under various diesel engine conditions [5,6] as well as of commercially available carbon blacks [7]. However, direct correlations between the important structural parameters and the reactivity under oxidative environments are lacking. This work focuses on a comprehensive structure and activity investi...

Structural analysis and chemical characterization of the DPM aggregates are important to improve the fundamental understanding about the relationship with their oxidation from diesel particulate filters (DPFs) [3]. This is a highly challenging problem due to the complex structure of the heavy fuel-derived carbonaceous materials [4]. Therefore, studies on detailed structure and chemical analysis of carbonaceous materials, as well as the correlations between various structural properties are lacking. In this work, structure and chemical nature of ten commercially available carbon black materials and diesel engine soot are investigated using X-ray Diffraction (XRD) and In Situ- XRD studies, Nitrogen sorption studies,...

Diesel cars contribute up to 53% of the passenger cars sold in the European market [[4]]. Despite the efficiency, durability, low operating cost, and reliability of diesel engines, Particulate Matter (PM) emissions remain responsible for various human health and environmental problems [[5]]. Diesel Particulate Filters (DPFs) are the most popular aftertreatment technology to meet the stringent PM emissions standards [[6], [7]]. However, periodic regeneration of DPF through efficient oxidation of PM or soot remains a major challenge, especially due to the complex nature of soot. Structure and oxidation activity of diesel soot is attributed to the combined effects of fuel, lubricating oil, operating conditions, and engine type[[8]]. A wide range of kinetic parameters have been reported for soot oxidation, e.g., activation energy lie...
