铝离子掺杂MIL-101(Cr)的制备及其VOCs吸附性能研究
Aluminum Ion Doped MIL-101(Cr):Preparation and VOCs Adsorption Performance
摘要
Abstract
Volatile organic compounds(VOCs)pose significant risks to environmental quality and human health.To enhance adsorption performance of adsorbents for VOCs,further improvement of the unsaturated metal centers becomes a key factor based on the principle that metal ions can be replaced in metal organic frameworks(MOFs).Here,a one-step solvothermal synthesis system was utilized to dope abundant,cost-effective,and environment friendly Al3+ions into MIL-101(Cr)for preparing Al-MIL-101(Cr).Morphologies and structures of MIL-101(Cr)and Al-MIL-101(Cr)samples,alongside the static adsorption performance for toluene,n-hexane,oil and p-xylene,were analyzed.Static adsorption capacities of toluene,n-hexane,oil,and p-xylene of MIL-101(Cr)were 0.676,0.621,0.451 and 0.812 g·g-1,respectively.When Al3+doping amount reached 0.75 mmol,Al-0.75-MIL-101(Cr)displayed maximum VOCs adsorption capacities(0.911 g·g-1 for toluene,0.755 g·g-1 for n-hexane,0.713 g·g-1 for oil,and 0.875 g·g-1 for p-xylene).The dynamic toluene adsorption behavior was assessed through single-component breakthrough curves.Both dynamic and static adsorption results demonstrate that Al-MIL-101(Cr)possesses excellent VOCs removal capabilities,which are attributed to the extensive specific surface area and augmented unsaturated metal sites.关键词
