Hydrolysis is the chemical breakdown of a compound due to reaction with water. It involves the splitting of a bond and the addition of the hydrogen cation and the hydroxide anion from the water. Here large, chemically complex compounds are broken apart with the addition of water into simpler compounds.
Photolysis on the other hand is the decomposition or separation of molecules by the action of light. This is a chemical reaction caused by light in which the bonds between atoms in a chemical compound are broken, resulting in the breakdown of the compound.
