英文摘要A bifunctional adsorption-catalysis system for the abatement of trace amounts of toluene was developed and realized by loading different amounts of Pt on mesoporous silica synthesized with ionic liquid with hydrophobic modification. The textural properties were evaluated using BET, contact angle, XRD, IR, XPS, TEM, and H-2-TPR techniques. The capability of the synthesized catalysts for room-temperature adsorption and low-temperature catalysis of toluene was appraised. The hydrophobic sample exhibited better toluene adsorption capacity of 53.1 mg g(-1) than SiO2-350 and 3.0Pt/SiO2 samples with 28.3 mg g(-1) and 18.9 mg g(-1), respectively. Furthermore, the hydrophobic sample showed increased maximum desorption temperatures of 52 degrees C in comparison with those at 44 degrees C and 37 degrees C, which acted as a good adsorption buffering system. 3.0Pt/SiO2-H showed the best toluene conversion capacity at T-90 = 129 degrees C, together with superior water vapor resistance and sequential capture-destruction performances. The increased bifunctional adsorption-catalysis performance with hydrophobic modification may be ascribed to the change in surface functional groups. The prepared system could be a valuable candidate material for adsorption-catalysis integration and assistance for VOCs elimination technology in barren waste gases.
