石墨烯/聚苯胺(GP)是一种高效、稳定、低成本的氧化还原电催化剂。然而,高温等复杂和苛刻的条件阻碍了GP的广泛应用。本文首次报道了一锅水热法合成具有优良电催化活性的GP纳米复合材料。聚苯胺与石墨烯的最佳质量比为4。GP的比表面积为82.0[式:见正文]m2[式:见正文]g[式:见正文],多孔骨架的平均孔径为4.45[式:见正文]nm。在碱性电解液中,GP作为ORR催化剂表现出较好的活性和近四电子途径。GP的起始电位和半波电位分别约为[式:见正文]0.13[式:见正文]V和[式:见正文]0.34[式:见正文]V,这与Pt/C催化剂的起始电位和半波电位接近。该方法提供了一种简便有效的获得GP的方法。
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.
