Effect of Nano-TiO2 on the Degradation of HC Modified by Different Metal Ions
In order to reduce the impact of exhaust gas on the surrounding environment of the road,as a new treatment technology,photocatalytic degradation technology has become a research hotspot.In order to improve the degradation efficiency of exhaust gas,nano-TiO2 and different concentrations of metal ions Fe3+,Ag+,La3+are doped by sol-gel method,and the self-made exhaust gas degradation reaction de-vice is used to open the exhaust gas degradation experiment.The results show that the catalytic efficiency of nano-TiO2 on HC is improved under the doping of Fe3+,Ag+and La3+,and the degradation efficien-cy of HC is the most obvious when the doping amount of La3+is1%,which can reach 10.9%.When the content of Fe3+is 1%,the degradation rate of exhaust gas can reach up to 25%.
