Abstract: A method for the large-scale synthesis of a zeolite-templated carbon (ZTC). The method includes the steps of: introducing a bed material comprising a zeolite to a fluidized bed reactor and heating the bed material to a temperature between 550° C. and 800° C.; fluidizing the bed material with a fluidizing gas and maintaining the temperature of the bed material between 550° C. and 800° C.; introducing an organic carbon precursor while fluidizing the zeolite for a period of time such that carbon is deposited on the zeolite by chemical vapor deposition to produce a zeolite-carbon composite; and treating the zeolite-carbon composite with an acid solution such that the zeolite template is dissolved and the ZTC is obtained.

Abstract: The present invention relates to a method of preparing a hierarchically porous polymer and a hierarchically porous polymer prepared thereby. The method comprises the steps of: (a) polymerizing an external oil phase of a high internal phase emulsion (HIPE) consisting aqueous droplets to produce a cross-linked block copolymer; (b) obtaining a macroporous polymer with interconnected macropores by removing the aqueous droplets; and (c) treating the obtained porous polymer with a base, thereby obtaining a hierarchically porous polymer having three-dimensional mesopores formed in the macroporous walls. According to the method, the macropore size and mesopore size of the hierarchically porous polymer can all be controlled. The hierarchically porous polymer prepared by the method can easily separate polymers having different sizes, and thus is highly useful in the polymer separation field.
