      A catalyst is something that is not used up in a reaction but helps to make the reaction more efficient by providing a surface or site for the reaction to take place

      A catalyst helps to speed up a reaction. The catalysts I work on help to remove harmful gases created by a petrol car engine into clean air which helps to improve the environment and people’s health.
