Abstract
A calcined hierarchical porous composite includes a carbon-based material, a bio-carrier material including biflavonoid and triterpenoid, and a layered double hydroxide. The carbon-based material includes graphene oxide, reduced graphene oxide, and a combination thereof. The bio-carrier material includes biflavonoid and triterpenoid, and is configured for carrying the carbon-based material therein so as to form a precursor structure. The layered double hydroxide has phosphate-specific active sites, and is formed on the precursor structure. A method for making the calcined hierarchical porous composite is also disclosed.
Claims9
A calcined hierarchical porous composite for removal of phosphate in water, comprising:
- a calcined carbon-based material selected from the group consisting of calcined graphene oxide, calcined reduced graphene oxide, and a combination thereof;
- a calcined solid bio-carrier material including biflavonoid and triterpenoid, and configured for carrying said calcined carbon-based material therein so as to form a calcined precursor structure;
- and
- a calcined layered double hydroxide having phosphate-specific active sites, and formed on calcined solid precursor structure, wherein calcination to obtain the calcined hierarchical porous composite is implemented under a temperature ranging from 250° C. to 350° C.
A method for making a calcined hierarchical porous composite, comprising the steps of:
- a) preparing a carbon-based material selected from the group consisting of graphene oxide, reduced graphene oxide, and a combination thereof;
- b) preparing a solid bio-carrier material configured for carrying the carbon-based material therein, and including biflavonoid and triterpenoid;
- c) mixing the carbon-based material with the bio-carrier material to permit the carbon- based material to be carried in the bio-carrier material so as to form a precursor structure;
- d) forming a layered double hydroxide on the precursor structure, the layered double hydroxide having phosphate-specific active sites;
- and
- e) subjecting the precursor structure formed with the layered double hydroxide to calcination, wherein step e) is implemented under a temperature ranging from 250° C. to 350° C.
