Photochemistry: where light meets chemistry
Photochemistry is the discipline that studies the chemical processes in which light plays a role. In this post, we do not aim to carry out a thorough analysis about photochemistry, but to provide a brief overview about some concepts we find interesting in this field. In the first place, we are going to describe the basic operation of a solar simulator, which is employed to reproduce natural sunlight. Then, we will explain two different types of reactions: photodegradation, focusing on polymers; and photocatalysis, describing two photocatalytic reactions (water splitting and CO2 reduction).
