 Definition A process that uses a substance (known as a catalyst) to accelerate the rate of a chemical reaction through an uninterrupted and repeated cycle of elementary steps until the last step regenerates the catalyst in its original form. [d] [e]

This CZ article was written from scratch. I found the WP article to be too technical and too advanced for an encyclopedic article. If this article contains any similar content from the WP article, it was not consciously copied from there. Milton Beychok 03:41, 10 April 2010 (UTC)


Cool article!!! Great diagrams too!!! --Thomas Wright Sulcer 04:22, 10 April 2010 (UTC)

Minor changes to lede

Added chemical engineering; as far as I know catalysis is most important for industrial processes. Chemists are interested in catalysis because of its industrial application. Moved forward the term "catalyst" (was now used before it was introduced). Added link to transition metals because many catalysts are transition metals. Added a sentence about economic importance. I have a source that quotes the trillions of dollars yearly turnover in catalytically produced products, but unfortunately my source is outdated, so I skip the actual numbers.--Paul Wormer 07:34, 11 April 2010 (UTC)

Many thanks, Paul for your edits. They have improved the article. Milton Beychok 16:28, 11 April 2010 (UTC)
