The effect of the degree of photochemical reduction of colloidal graphene oxide (GO) on its ability to stabilize graphite microparticles and carbon nanotubes in aqueous solutions was determined. If photoreduced GO is used as stabilizer dispersions of graphite particles with an average size of 2-3 mu m and nanotubes with lengths of up to 1 mu m are formed. The amount of dispersed graphite particles increases many times with increase in the degree of reduction of the GO. The relationship between the amount of dispersed nanotubes and the degree of photoreduction of the GO passes through a minimum as a consequence of photoinduced removal of the functional groups of the GO and of decrease in its ability to interact with the partially hydroxylated surface of the nanotubes.
