Temperature (200–283 K) dependence of methane adsorption onto hydrophobic nanosilica/arginine composite at various hydration

Temperature (200–283 K) dependence of methane adsorption onto hydrophobic nanosilica/arginine composite at various hydration

It has been assumed that nanoparticle/aggregate/agglomerate structure, texture and surface characteristics of hydrophobic nanosilica AM1 treated with certain amounts of arginine and water may provide better conditions for methane adsorption compared to AM1 alone. Nanosilica and composites are charac...

Zusammenfassung:It has been assumed that nanoparticle/aggregate/agglomerate structure, texture and surface characteristics of hydrophobic nanosilica AM1 treated with certain amounts of arginine and water may provide better conditions for methane adsorption compared to AM1 alone. Nanosilica and composites are characterized using adsorption, desorption, microscopic, spectroscopic, XRD, SAXS, and quantum chemistry methods. The 1H NMR spectroscopy (at 200–283 K) and cryoporometry (T
