“…Understanding the relationship between oxygen vacancies and catalytic performance is pivotal in catalyst design. Catalytic performance can be improved by changing catalyst morphology, composition, and doping levels [24] . The methods of catalytic performance evaluation are as follows: The catalytic performances of soot oxidation are accessed by Temperature‐Programmed Oxidation (TPO) reaction or Thermal Gravity Analysis (TAG) using model soot particles (loose or tight contact with catalysts) and reaction gas (O 2 , NO (presence or absence) balanced with N 2 ).…”

Environmental issues exert a significant influence on the human life. Soot particles have attracted attention as a major source of pollution. Significant progress has been made in the research of efficient soot combustion catalysts. The distinctive bonding properties on the 4f orbitals of rare earth elements exhibit excellent catalytic performance for soot combustion. This comprehensive review explores recent advancements in the design of catalysts based on rare earth oxides, with a specific focus on various catalytic materials (La‐based, Ce‐based, Pr‐based and other rare earth elements), synthesis methods, catalyst morphology, catalytic performance and the intricate mechanisms governing their performance in catalytic soot combustion. The activity and selectivity of different rare earth catalysts in various reaction atmospheres are also summarized in the article. Finally, the challenges associated with rare earth oxide‐based catalysts and their potential for future development in the soot combustion are highlighted. This review establishes a fundamental basis for the further design of catalytic materials that exhibit enhanced efficiency and stability.
