Carbon tetrachloride (CCl₄) is a type of volatile organic compound (VOC) that was once widely used as a refrigerant and cleaning agent, but is now strictly regulated due to its toxic properties. However, its environmental impact remains a concern and recent reports indicate that CCl₄ emissions have been detected in some countries. Therefore, the development of CCl₄ decomposition technology is critical, and holds promise for its application in decomposing and neutralizing various VOCs.
