Photocatalytic water splitting is a process that uses photocatalysis for the dissociation of water (H 2 O) into hydrogen (H 2) and oxygen (O 2). The inputs are light energy , water, and a catalyst(s). The process is inspired by Photosynthesis, which converts water and carbon dioxide into oxygen and carbohydrates.
