摘      要：The applicability of ultraviolet-light emitting diodes(LEDs)as a light source for photocatalysis using granular activated charcoal (GAC)impregnated with transition metal-enhanced photocatalysts for the control of volatile organic compounds(VOCs)was investigated. Two target compounds(toluene and methyl mercaptan)were selected to evaluate the removal activities of the TiO2/GAC *** photocatalysts were prepared by a sol-gel *** trimethoxy silane was added as a precursor sol solution to bind the photocatalyst with the ***(Zn 2+ ,Fe 3+ ,Ag + ,and Cu 2+ )enhanced TiO2/GAC composites were prepared and tested for their photocatalytic activities under 400 nm LED *** specific surface area(SSA)and the surface chemical composition of the prepared composites were *** SSAs of all the impregnated composites were similar to those of pure *** field emission-scanning electron microscopy and energy dispersive spectroscopic analysis confirmed that titanium and the impregnated metals were deposited on the surface of the *** breakthrough time for GAC toward toluene or methyl mercaptan gas increased upon photocatalytic impregnation and LED *** different binders affected the breakthrough time of the TiO2/GAC composite and the addition of zinc oxide to TiO2 increased the VOC removal capacity of the GAC composite.
