Synthesis of MIL-100(Fe) at low temperature and atmospheric pressure

Mil-100(fe),a mesoporous metal-organic framework (mof),has a large bet specific surface area and pore volume with the presence of a significant amount of accessible lewis acid metal sites upon dehydration. the structural characteristics of mil-100(fe) make it a good candidate for potential applications in gas storage,separation,and heterogeneous catalysis. mainly,this mof is obtained by the hydrothermal synthesis in a teflon-lined autoclave at high temperature (>150°c) under static conditions. however,this method has several disadvantages such as high temperature,high (autogenous) pressure,long time,and comparable low mof yield. therefore,development of a facile method for synthesis of mil-100(fe) is vitally important for fundamental understanding and practical application. herein,mil-100(fe) is synthesized by a facile low-temperature (<100°c) synthesis route at atmospheric pressure by reaction of metallic iron and trimesic acid in water. due to our synthesis is conducted with agitation,higher mof yield (>90%) still could be achieved,suggesting that this simple and energy saving method has the potential to be used practically. © 2013 jing shi et al.
