Photocatalysis is a process where light energy, usually from ultraviolet (UV) sources, is used to accelerate a chemical reaction through the activation of a catalyst. The ability to degrade harmful substances and improve material properties under light exposure makes photocatalysis a key technology in advancing sustainable solutions to industrial problems. Plasma treatment serves multiple purposes in photocatalysis. It can clean material surfaces to create a pristine base, modify surface chemistry to enhance coating adhesion, and physically alter material properties through etching.
