SELF REGENERATING CATALYSTS: Platinum Group Metal Perovskite Catalysts

Parth K. Vagholkar

Abstract :

 Until the advent of self?regenerating catalysts, catalytic deactivation proved to be detrimental in the progress of innumerable reactions. Various potentially profitable industries were not considered to be feasible because catalytic deactivation hindered the formation of the industrial products. Catalyst deactivation would require a need of greater catalyst metal, most of them being costly had financial ill effects on the industries. Therefore there was a need for such catalysts which would not deactivate with time and thus would continue to have the same activity throughout the reaction. This need was eventually satiated with the invention of self?regenerating catalysts. These type of catalysts adapt to various external conditions without a decrease in their catalytic activity. The Platinum Group Metal – Perovskite Catalyst is one such self?regenerating catalyst. By its self?regenerating mechanism, it has successfully ameliorated automobile industrial reactions and also many other organic reactions. The PGM?Perovskite Catalyst operates at very high temperatures (at which conventional catalyst start deactivating) without undergoing any deactivation from sintering, aging and coking. Moreover due to their high activity, versatile and stable structure and low PGM content required, they offer greater advantages over the conventional catalysts. Hence knowledge of such catalysts would give rise to greater developments in the future and thus alleviate many of our problems. Some of the typical applications of these catalysts in the automobile industries and organic chemistry, their working mechanism, structure and preparation are reviewed in this article.
