One-step synthesis of magnetic and porous Ni@MOF-74(Ni) composite

Tingting Xu,Xudong Hou,Shengjun Liu,Bo Liu

We demonstrated a facile and efficient method for the preparation of a magnetic and porous Ni@MOF-74(Ni) [Ni 2 (DOBDC), DOBDC = 2, 5-dihydroxyterephthalate] composite by one-step solvothermal reaction of Raney Ni and DOBDC. Ni in the reaction not only acted as the core of the composite, but also provided metal source for the formation of MOF-74(Ni). The Ni@MOF-74(Ni) composite exhibits both magnetic characteristics and high porosity, enabling it an efficient candidate for dye removal and target drug delivery system. The adsorption amount of rhodamine b reached up to 177.8 mg g −1 , and 4.1 mg g −1 for ibuprofen.
