Fabrication of hybrid magnetic HKUST-1 and its highly efficient adsorption performance for Congo red dye

A facile and efficient strategy for the preparation of a hybrid magnetic metal-organic framework HKUST-1 via chemical bonding approach is reported. The composite features both magnetic separation characteristics and high MOF porosity, making it an excellent adsorbent for removal of hazardous anionic Congo red dye from effluents.
