NOVEL POROUS AMORPHOUS SILICA AND PRODUCTION METHOD THEREFOR
Disclosed are: porous amorphous silica having micropores and an acid strength of at least 0.4 Band area / a.u.
a production method for porous amorphous silica including a step in which iron oxides generated by microorganisms are treated with an acid
a solid acid catalyst and an adsorbent, each containing porous amorphous silica
an organic-inorganic composite material obtained by chemically modifying the porous amorphous silica with an organic group
and a catalyst-organic-inorganic ternary composite material obtained by immobilizing the catalyst upon the organic-inorganic composite.
