Cold water and large pieces.
The opposite of catalytic catalysts [that enhance the rate of a specific chemical reaction] are catalytic poisons [that generally halt a particular chemical reaction].
An example is the introduction of the auto-exhaust catalytic converter: the catalyst was Palladium which was being poisoned by the Lead in the gasoline so we needed to convert to unleaded gas!

Speed up the rate of a chemical reaction
Particle size
You suck your mama's balls
Amylase helps speed up breakdown of starch molecules.
Reactions are speed up by enzymes. Enzymes are type of proteins
Activation energy is lowered to speed up a chemical reaction.

to speed up a chemical reaction
A catalyst can speed up a chemical reaction.
Heat would speed up the reaction, while cold would slow the reaction.
Anything that is added to a chemical reaction that's intended to speed up the reaction - is a catalyst.
Enzymes are proteins which speed up chemical reactions.
Enzymes are proteins that speed up chemical reactions.
The particle size is decreased so that you can speed up a chemical reaction. Proteases is the enzymes that break down proteins.
Speed up the rate of a chemical reaction
No a catalyst is unchanged by a chemical reaction, it does however serve to speed up the rate of the reaction.
Ensymes speed up a chemical reaction by acting as organic catalyst, a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change.
