摘要: This study delineates a simple and versatile approach for the removal of nitrogen monoxide (NO) volatile organic vapors over composites titanium dioxide (TiO2) catalyst/zeolite adsorbent under ultraviolet (UV) irradiation at ambient temperature. The catalytic adsorbents with different TiO2/H-ZSM-5 zeolite ratios were prepared by insipient wetness impregnation method. It was found that 60%/40% weight ratio composite is most effective can achieve 90% efficiency NO acetone vapors. also showed better long-term activity than bulk TiO2 photocatalyst or adsorbent. experimental results revealed photocatalytic decomposition dramatically enhanced in presence acetone. promoted oxidation humid conditions. Furthermore, co-existence gaseous stream could reduce acid accumulation on surface catalyst as confirmed Fourier-transform infrared spectroscopy. Thus, TiO2/zeolite have high potential multiple air pollutants indoor environment.
