Graphene/polyaniline (GP) is an efficient, stable and low-cost electrocatalyst for oxidation reduction reaction (ORR). However, complex and demanding conditions such as high temperature hamper the wide application of GP. Here we first report a one-pot hydrothermal method for synthesis of GP nanocomposites with excellent electrocatalytic activity in ORR. The optimum mass ratio of polyaniline to graphene was 4. GP has a specific area of 82.0[Formula: see text]m2[Formula: see text]g[Formula: see text] and porous skeleton with the average pore size of 4.45[Formula: see text]nm. GP exhibits better activity and a nearly four-electron pathway as ORR catalyst in alkaline electrolyte. The onset potential and half-wave potential of GP is about [Formula: see text]0.13[Formula: see text]V and [Formula: see text]0.34[Formula: see text]V, respectively, which is close to that of Pt/C catalyst. The method provides a facile and effective way to obtain GP.
