摘要: The porous hierarchical MgO with superb adsorption properties has been synthesized by a facile and scaled-up method. X-ray powder diffraction, electron microscopy, Fourier transformed infrared, N2 adsorption–desorption were carried out to study the microstructure of as-synthesized precursor product. It demonstrated that as-prepared structure high specific surface area (148 m2 g–1). And sample exhibited super properties, maximum capacity 2409 mg g–1 for Congo red, which is highest reported value. Moreover, process red on was systematically investigated, found obey pseudo-second-order rate equation Langmuir model.
