Graphite oxide silylated by 3-aminopropylmethyldiethoxysilane was used an adsorbent of formaldehyde from gas phase at low concentration. The amount of formaldehyde adsorbed on this adsorbent was much higher than that on activated carbon, even when water molecules are preadsorbed. The utility of the amino groups seemed to be higher for the sample with lower contents of organic component between the...
Graphite oxide was silylated by 3-aminopropylethoxysilanes under various reaction conditions. Two types of layered materials were obtained when 3-aminopropyltriethoxysilane was reacted with graphite oxide. One obtained at lower temperatures was 3-aminopropyltriethoxysilane-intercalated graphite oxide with an interlayer spacing of 1.27nm, in which amino groups of 3-aminopropyltriethoxysilane were bonded...
