A substance by itself will not slow down a chemical reaction; factors require change, such as cooling the reactants or lowering the concentration, to do so. Adding another chemical or substance that happens to slow a reaction often does so by actually interfering with the reaction and replacing or preventing it outright, and there is not a name for chemicals that do this -?inhibitor?-, since a chemical may do this to one reaction, but be a catalyst to another.
Added:
decrease surface area/ remove catalyst/ decrease temperature/ decrease concentration/ add inhibitor/ dilute reactants/ separate reactants/
Negative catalysts are substances which slows down chemical reactions.
They are called 'inhibitors'
The substance that slows down a chemical reaction is an inhibitor. Instead you could also call an inhibitor an anticatalyst.-anticatalyst `antee'katlist1. (chemistry) a substance that retards a chemical reaction or diminishes the activity of a catalyst
Usually:decreasing concentrationlowering the temperaturesometimes lowering pressureremoving any catalyst
In chemistry a catalyst is a substance which, when added to other substances, allows them to change while itself remaining unchanged.
inhibitor
In general, a material that decreases the rate of a chemical reaction is called an inhibitor.

if at the end of the chemical THAT substance is unchanged .That substance is a catalyst. If it slows donw the reaction, it is called an inhibitor.
an inhibitor
Chemical reactions can be either sped up or slowed down by catalysts.

* Reactants: the initial compounds in a chemical reaction. * Products: the final compounds in a chemical reaction. * Catalyst: a chemical compound which help the chemical reaction but not react with the other compounds.

Reduces the activation energy of the reaction, which speeds up the progress of the reaction It increases the rate of a chemical reaction. However a true catalyst is not consumed in the reaction.
An inhibitor decreases the reaction rate
negative catalyst.
