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

Abstract Amino-functionalized metal-organic frameworks have attracted much attention because of their potential applications in many fields such as catalysis, adsorption and separation of CO 2 , further modification. In this work, we report that amino-functionalized MIL-101(Cr) with a large BET surface area of 3262 m 2 /g has been successfully synthesized by the reduction of MIL-101(Cr)-NO 2 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.
