The paper describes the effect of low-temperature annealing in air on the composition and structure of graphene oxide aerogel. It has been found that the concentration of carbon in the aerogel sharply increases, i.e., its carbonization occurs, already at a temperature of 175 degrees C. At the same time, both the outer shape of the aerogel granules and the internal porous structure are preserved.
