MATERIAL HAVING SELECTIVE ADSORPTIVITY OF INORGANIC MATERIALS AND PRODUCTION METHOD THEREOF

摘要

The present invention relates to a porous, selectively adsorptive material selected from an Al, Ti or Zr type oxide and having a mean pore diameter of not greater than 5 nm, and a porous, selectively adsorptive material comprising an Si oxide and having a mean pore diameter of 1 to 5 nm. The material of the present invention has particularly excellent selective adsorptivity of Nox in an alumina type material.
