NEW NANOPOROUS ADSORBENTS
New trials to improve adsorption kinetics of zeolites and activated carbon fiber(ACF)s with addition of mesopores with the aid of templating and chemical modification are described. The templating with carbon aerogel and resorcinol-formaldehyde gels added mesopores of 10-12 nm in width to ZSM-5, NaA, and NaY. The steam reactivation of ACF with Ca(NO3)2 provided mesopore-added ACF, whose adsorption rate for methylene blue was remarkably improved. The clathrate compound formation mechanism of metal organic framework of copper with CH4 and CO2 was shown for gate adsorption that induces predominant adsorption and desorption at the definite pressures.The adsorption of H2 and D2 on single wall carbon nanohorn (SWNH) was examined over the temperature range of 20 K to 77 K. The adsorption amount of D2 was larger than that of H2, which was explained by the quantum molecular sieving effect. Other adsorption abilities of SWNH assemblies were described.
