摘要: Abstract Hierarchical MgAl–layered double hydroxide (MgAl–LDH) was fabricated both on the external and interlayer surfaces of natural mineral vermiculite (VMT) via in situ epitaxial growing technique. The fabrication MgAl–LDH/VMT achieved by lattice match VMT with MgAl–LDH, which indicates MgAl–LDH can adopt a tilted orientation to surface. Compared traditional hierarchically structured exhibits higher sorption-regeneration performance for Cr(VI), since specific surface area transfer channel are significantly enhanced due its porous 3D framework. hierarchical be potentially used as adsorbent waste water treatment.
