A method to fabricate the porous glass ceramic microspheres is reported. The fabricated glass microspheres and the porous glass ceramic microspheres are characterized by scanning electroscopy (SEM) and transmission electron microscopy (TEM), respectively. The sizes of glass microspheres and the pore diameters of the porous glass ceramic microspheres are estimated, respectively. The adsorption properties of the porous glass ceramic microspheres are characterized by adsorption isotherm, surface area and pore distribution with the help of N2 adsorption. The adsorption isotherms of phenol based on which effective means to increase the adsorption of porous glass ceramic microsphere are tested.
