Abstract: Sequential synthesis of anatase modification titanium oxide nanoparticles on reduced graphene oxide in supercritical isopropanol is described. In this case, only graphene oxide was reduced to reduced graphene oxide. A one-stage method (one-pot) was also developed for the preparation of titanium oxide nanoparticles on reduced graphene oxide, where supercritical isopropanol was the graphene oxide reducing agent and the reaction medium. The resulting nanocomposites were studied using X-ray phase analysis, transmission electron microscopy, and atomic force spectroscopy methods

Keywords: nanoparticles, titanium oxides, anatase, graphene oxide, reduced graphene oxide
