The term divergent catalysis describes different catalytic chemical reactions that occur with the same substrates (reactants) under controllable conditions, especially using different catalysts. Various substrates were found to work with versatile reactivity under different catalytic conditions, resulting in ...

Catalyst, in chemistry, any substance that increases the rate of a reaction without itself being consumed. Enzymes are naturally occurring catalysts responsible for many essential biochemical reactions. In general, catalytic action is a chemical reaction
In addition to being used in health care, biotechnology has proved helpful in refining industrial processes through the discovery and production of biologicalenzymesthat spark chemical reactions (catalysts); for environmental cleanup, with enzymes that digest contaminants into harmless chemicals and then di...
Types of catalysts A catalyst is a chemical compound which makes the reaction occur more quickly by reducing the reaction’s activation energy barrier. During the reaction it isn’t eaten. Homogeneous catalyst –Homogeneous catalysts are usually soluble metal salts or compounds that are dissolved in...
The type of catalyst used in a dehydration synthesis reaction depends on the types of molecules involved in the reaction. In some cases, heat, alcohols, or acids can be used as catalysts. Looking more in-depth at the specific steps involved in a dehydration, or condensation, reaction, two ...
