Photochemical Reaction - Definition & Theoretical Concepts

Photochemical Reaction Examples. The majority of processes on the other hand that we see in nature are photochemical ones. Our own ability to see the things in the world using the eyes is nothing but a photochemical reaction where a retinal that happens to be rhodopsin (photoreceptor cell molecule) changes its shape after sunlight or light absorption.

Photocatalysis - Wikipedia

In chemistry, photocatalysis is the acceleration of a photoreaction in the presence of a catalyst.In catalysed photolysis, light is absorbed by an adsorbed substrate. In photogenerated catalysis, the photocatalytic activity (PCA) depends on the ability of the catalyst to create electron–hole pairs, which generate free radicals (e.g. hydroxyl radicals: •OH) able to undergo secondary reactions.
