Catalysts generally react with one or more reactants to form intermediates that subsequently give the final reaction product, in the process of regenerating the catalyst.Ĭatalysis may be classified as either homogeneous, whose components are dispersed in the same phase (usually gaseous or liquid) as the reactant, or heterogeneous, whose components are not in the same phase. If the reaction is rapid and the catalyst recycles quickly, very small amounts of catalyst often suffice mixing, surface area, and temperature are important factors in reaction rate.
Catalysts are not consumed in the reaction and remain unchanged after it. It can also remove formaldehyde from the air.Ĭatalysis ( / k ə ˈ t æ l ə s ɪ s/) is the process of increasing the rate of a chemical reaction by adding a substance known as a catalyst ( / ˈ k æ t əl ɪ s t/). An air filter that uses a low-temperature oxidation catalyst to convert carbon monoxide to less toxic carbon dioxide at room temperature.
