Porous ceramics catalyst carrier possessing two-dimensional nanopores and preparation method thereof
The invention discloses a porous ceramics catalyst carrier possessing two-dimensional nanopores and a preparation method thereof. A main component of the catalyst carrier is one of Al2O3, SiO2 or TiO2, acrylic acid surface-modified bacterial cellulose is taken as a pore forming agent, porosity is 5-65%, the aperture is 50-300nm, and the specific surface area is 20m<2>-130m<2>/g. The porous ceramics catalyst carrier is prepared by the following steps: processing blank, modifying bacterial cellulose, sintering embryoid body and modifying the embryoid body. The porous ceramics catalyst carrier contains a two-dimensional nanopores structure with two open-ended ends; the preparation method of the porous ceramics catalyst carrier is simple, the pore forming agent is a natural nanometer level organic matter, no toxic substance is generated during production and usage processes, and the preparation method accords with environmental protection requirements.
