Removal of formaldehyde from gas phase by silylated graphite oxide containing amino groups

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...

Description
Summary: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 layers and larger interlayer spacings.
