Nanoporous cellulose foams have been successfully prepared by a procedure in three steps: (i) dissolving in a room temperature ionic liquid (1-butyl-3-methylimidazolium chloride); (ii) coagulation in water; (iii) rapid freeze drying using liquid N 2 . The results show that the foam had a 3D open fibrillar network structure with the specific surface area as high as 186.0 m 2 /g and...
A carbon-coated nano-MgO has been prepared with the assistance of sucrose and characterized by adsorption methods, X-ray diffraction method (XRD) and Scanning electron microscopy (SEM). Sucrose can both prevent the agglomeration of the synthesized Mg(OH) 2 and act as the carbon source for surface coating of the MgO nanoparticles, and both crystallite sizes and carbon contents of the composites...
