AI overview

Catalysis is the process of speeding up a chemical reaction by adding a substance called a catalyst, which itself remains unchanged and unconsumed by the reaction. Because catalysts aren't used up and can be recycled, small amounts of them can make reactions happen much faster, which is why they're valuable in industrial applications and environmental solutions like air filtration.

Katalys (av grekiska κατάλυσις, katálysis ”upplösning”) är den inverkan som en katalysator har på en kemisk reaktion. Begreppet valdes 1835 av Jöns Jacob Berzelius i analogi till "analys". Som "katalysator" betecknar man substanser som underlättar kemiska eller fysikaliska förändringsprocesser utan att tillföra energi till processen. Katalysatorn förbrukas inte under processen utan finns kvar oförändrad och kan fortsätta att verka, därför behövs ofta en mycket liten mängd katalysator. Katalysatorer av varjehanda slag förekommer i en mängd olika organiska och oorganiska sammanhang. Enzymer, som reglerar cellers funktioner och därmed de fundamentala livsprocesserna, är exempel på biologiskt viktiga katalysatorer.
