The worldwide effort to reduce the harmful effects of automotive exhaust has witnessed impressive progress over the past few decades. There has been a sustained interest in the development of new catalysts. Three-way catalysts (TWCs) constitute the most satisfactory and efficient solution to reduce pollutant emissions from automobiles. In this context, the research focus has been aimed at the development of more efficient catalyst with high level of heat resistance to ensure stability and reliability in long-term service. Cerium oxide was recognized as indispensable to the success of TWCs,...
