Synthesis of amino-functionalized MIL-101(Cr) with large surface area

Amino-functionalized metal-organic frameworks have attracted much attention because of their potential applications in many fields such as catalysis, adsorption and separation of CO2, further modification. In this work, we report that amino-functionalized MIL-101(Cr) with a large BET surface area of 3262 m2/g has been successfully synthesized by the reduction of MIL-101(Cr)-NO2 prepared under solvent-free conditions. Additionally, it has been demonstrated that the obtained material with high surface area exhibited superior catalytic activity in Henry reaction.
