ABSTRACT:
A heat resistant layered porous silica having a honeycomb porous structure comprises a plurality of waved or bent sheet layers of crystalline layered silicate superposed one after another, and the neighboring sheets are partially bonded by siloxane bonding. The spacing between the neighboring sheet layers is narrowed toward the bonded portions and expanded at other portions to thereby form fine pores. The layered porous silica contains alkali metal ions in an amount of 0.2% by weight or less and has a specific surface area of 1,000 m.sup.2 /g or more.
The layered porous silica has a large specific surface area, and exhibits an excellent heat resistance and adsorption of organic substances such as fuel.
