Research progress of photocatalytic degradation of formaldehyde and VOC
With the continuous development of industrialization,the sources of formaldehyde and VOC are more and more extensive.Because of many hazards to the environment and human body,the treatment of formaldehyde and VOC has become the focus.Since the 1970s,the application of photocatalysts in environmental governance has gradually increased.The photocatalyst has a wide source of raw materials and mild reaction conditions,which can provide technical support for the treatment of formaldehyde and VOC.Photocatalyst can be divided into organic,inorganic and organic inorganic composite photocatalyst.Based on the different classification of photocatalysts,this paper summarizes the current research situation of the treatment of formaldehyde and VOC by photocatalysts,and looks forward to the future development direction of photocatalysis.
