Evaluation on effectiveness of photocatalyst in degradation of air pollutants

Objective To determine the effects of photocatalyst in degradation of air pollutants.Methods The sealed cabinets were used to obseve the effects of degradation on formaldehyde,ammonia.benzene,xylene by photocatalyst at differnet time points.Results Photocatalysthad very strong effects of degradation on formaldehyde,ammonia,benzene,and xylene.There were more than 90%decomposed on formaldehyde,ammonia and xylene and more than 70% in benzene by photocalyst.Photocatalyst also possessed to decompose the formaldehyde releasing from board of furniture.Conclusion Photocatalyst could decompose air pollutants such as formaldehyde,ammonia,benaene and xylene and its mechanism need to be studied further.
