Hi Geoff,
There are "negative" catalysts that can raise the activation energy of
chemical reactions. One example is the oxidation inhibitors blended with rubber
tires to prevent cracking of the rubber. When UV (sunlight) shines on the rubber
surface, the inhibitor prevents the carbon bonds the rubber form breaking.
