Summary: | ► W-doped TiO2 was synthesized and immobilized on FGC. ► The material was tested for BTEX degradation under visible region. ► It showed higher efficiency than P25 for BTEX degradation. ► 100% of BTEX was removed by using this catalyst.
W-doped TiO2 were immobilized on fiberglass cloth (FGC). The catalyst possessed small crystallite sizes with a red-shift on an absorption edge. Good dispersion was observed over the immobilized catalyst. The photocatalytic degradation of gaseous BTEX was conducted in a flow reactor under day-light fluorescent. Parameters including gas flowrate, catalyst loading, initial concentration and relative humidity (%RH) were investigated. The prepared catalysts showed higher efficiency than that of TiO2 approximately 18, 3, 3 and 2.5× for benzene, toluene, ethylbenzene and o-xylene, respectively. The condition to achieve 100% BTEX removal was found at 20min/ml, catalyst loading 0.1mg/cm2 and 30% RH. |
