Photocatalytic Degradation of Formaldehyde Driven by Discharge Plasma

Chen Li Ou Rui-kun Yan Zong-cheng Wang Hong-lin Ma Zhen(School of Chemistry and Chemical Engineering,South China University of Technology,Guangzhou 510640,Guangdong,China)  
This paper deals with the photocatalytic degradation of formaldehyde driven by dielectric barrier discharge plasma,with TiO2 as the photocatalyst,and reveals the effects of discharge voltage,catalyst support,calcination temperature and transition metal ion doping on the degradation efficiency.The results indicate that photocata-lyst TiO2/γ-Al2O3 significantly improves the degradation rate of formaldehyde and the product selectivity,that the degradation rate increases with the discharge voltage but decreases with the increases in calcination temperature,that the degradation rate is up to 83.8% at a discharge voltage of 20.7 kV and a calcination temperature of 400 ℃,that the plasma-driven anatase TiO2 system is of a degradation efficiency higher than that of the plasma-driven rutile one,that,with the doping of Mn ions,the degradation rate of the plasma-driven system increases by 45.7%,while the mass concentration ratio of CO to CO2 as well as the amount of O3 respectively decrease by 42.5% and 39.4%.
