Benzene, toluene, ethylbenzene, and p-xylene (BTEX) are hazardous volatile organic compounds mostly released from fuel combustion, paint gas emissions, and biomass burning. In this work, it is studied the BTEX sorption influence on the surface reactivity of a new kind of nanoporous composite, prepared via an in situ functionalization of SBA-15 with a Mg–Al calcined hydrotalcite (HTC). During its preparation, Mg/Al mixed oxides are indeed formed and dispersed on the SBA-15 surface with non-blockage porosity. Furthermore, the physicochemical surface properties are exalted from its precursors and it is synergistically favorable for the BTEX sorption at low pressure and temperature.

BTEX在SBA-15和煅烧水滑石的纳米多孔复合物中的吸附。

苯，甲苯，乙苯和对二甲苯（BTEX）是有害的挥发性有机化合物，主要从燃料燃烧，油漆气体排放和生物质燃烧释放。在这项工作中，研究了BTEX吸附对新型纳米多孔复合材料表面反应性的影响，该复合材料是通过SBA-15与Mg-Al煅烧水滑石（HTC）原位官能化制备的。在其制备过程中，确实形成了Mg / Al混合氧化物，并以无阻塞的孔隙形式分散在SBA-15表面上。此外，从其前体可以提高其物理化学表面性能，并且在低压和低温下协同有利于BTEX的吸附。
