The effect of the temperature of graphene oxide reduction on low-temperature sorption of ⁴He
The sorption of⁴He by graphene oxide powders thermally reduced at T = 200, 300, 500, 700, 900 ºC has been investigated in the interval 1.5–290 K. The measured dependence of the quantity of sorbed helium upon the reduction temperature shows up as a nonmonotonic curve. The highest quantities of heli...

| description |
The sorption of⁴He by graphene oxide powders thermally reduced at T = 200, 300, 500, 700, 900 ºC has been
investigated in the interval 1.5–290 K. The measured dependence of the quantity of sorbed helium upon the reduction
temperature shows up as a nonmonotonic curve. The highest quantities of helium were sorbed by the
samples reduced at T = 300 and 900 ºC. It is assumed that the thermal reduction of graphite oxide by heating it to
300 ºC causes evaporation of the water intercalated in the spacings of the carbon layers, this results in exfoliation
of the graphene planes, which enhances the sorptive capacity. Heating the samples to 900 ºC generates numerous
defects in the carbon planes, as a result, the interlayer spacings become accessible for sorption, which enhances
the sorptive capacity.
