Abstract: The definition,various sources,harm to the human body and the environment,and the commonly used treatment technology of volatile organic compounds (VOCs) are described briefly.The types and harms of main VOCs in indoor and outdoor are classified and summed up.The principle and method of the photocatalytic technology that is used to treat with VOCs are summarized.The research situation for photocatalytic treatment of aldehyde and aromatic VOCs is reviewed and analyzed briefly.Based on analysis,the problem that the photocatalytic technology is short of degradation mechanism is proposed and the future research directions for photocatalytic technology are suggested and prospected.
