In this review, we have systematically discussed diesel particulate composition and its formation, understanding of which is essential to design the effective catalyst compositions. The most commonly used after treatment strategies such as diesel oxidation catalysts, diesel particulate filters, and partial flow filters are described followed by chronological and category-wise discussions on various groups of reported soot oxidation catalysts. A detailed review is also presented on mechanistic and kinetics aspects of non-catalytic direct particulate matter (PM) or soot oxidation in air/O₂ and NO₂. Recent progress in catalyst development with a focus on the low-cost catalyst for diesel PM oxidation has been given more emphasis considering their renewed importance.

在这篇综述中，我们系统地讨论了柴油微粒的组成及其形成，对柴油微粒组成的理解对于设计有效的催化剂组成至关重要。描述了最常用的后处理策略，例如柴油机氧化催化剂，柴油机颗粒过滤器和部分流过滤器，然后按时间顺序和类别对已报道的各种烟灰氧化催化剂进行了讨论。还对空气/ O ₂和NO ₂中非催化性直接颗粒物（PM）或烟尘氧化的机理和动力学方面进行了详细综述。考虑到其新的重要性，更加关注催化剂开发的最新进展，重点是用于柴油PM氧化的低成本催化剂。
