Abstract:

This paper presents an experimental approach to study purification effect of automobile exhaust. Sol-gel method was used to prepare Fe3+ modified Titanium dioxide (TiO2). Purification tests were conducted in a self-developed instrument to study catalytic effects of TiO2 doped with different contents of Fe3+ through degradation rate. The modification mechanism was studied by X-ray diffraction (XRD) scanning. Results showed that doping iron ion had improved the light catalytic performance of nanometer through inhibiting the growth of TiO2 grain size. TiO2 doped with 0.1% iron ion showed the best catalytic effect. The degradation rates of CO and CO2, HC and NOX were 6.9%, 7.9%, 2.3% and 14.9% higher than the unmodified TiO2 under ultraviolet light conditions, respectively; 0.6%, 0.6%, 2.3% and 8.2% higher than the unmodified under incandescent light conditions, respectively.
