Abstract
Strengthening electrical conductivity and multiple atomic interaction are benefit for improving activity of oxygen evolution reaction (OER). Herein, we synthesized Fe-Doped NiSe2 nanospheres distribute on reduced graphene oxide sheets (Ni0.7Fe0.3Se2/rGO). The optimum ratio (30%) of rGO was ascertained by comparing the properties of catalysts with different rGO amounts. In alkaline electrolyte, the Ni0.7Fe0.3Se2/rGO-30% owns the better OER performance than those of Ni0.7Fe0.3Se2 and NiSe2, ascribed to the unique architecture that Ni0.7Fe0.3Se2 nanospheres decorate rGO. In the architecture, the rGO matrix increases conductivity, enlarges transfer rate of ions and electrons and promotes dispersion of Ni0.7Fe0.3Se2. In addition, multiple atomic interaction of Ni/Fe atoms and the synergistic effect between the Ni0.7Fe0.3Se2 and rGO enable the compound to be an efficient OER catalyst. Through the rational analysis, Ni0.7Fe0.3Se2/rGO-30% hybrid is promising as an effective non-noble metal catalyst for OER application.
