Assembling Co9S8 nanoflakes on Co3O4 nanowires as advanced core/shell electrocatalysts for oxygen evolution reaction

N-doped CoO nanowire arrays as efficient electrocatalysts for oxygen evolution reaction

“…It is widely recognized that materials based on the transition metal composites, including metal oxides [12][13][14][15][16] , sulfides [17,18] , phosphides [19,20] , nitrides [21,22] and selenides [23,24] , are the most promising alternatives owing to their high electrocatalytic performance and excellent electrochemical stability for OER. Of these candidates, cobalt oxides spark intense great interest for OER catalysis owing to their facile preparation and high theoretically electrocatalytic activity [25][26][27] .…”

Component‐Tunable Rutile‐Anatase TiO2/Reduced Graphene Oxide Nanocomposites for Enhancement of Electrocatalytic Oxygen Evolution

“…Based on almost the same RGO in RAG2, RAG3 and RAG4, the ratio of rutile and anatase in these nanocomposites is believed to further affect the OER activity. The effective electrochemical active surface areas (ECSA) were also estimated by testing the double‐layer capacitance based on the cyclic voltammograms results at different scan rates –. ECSA of RAG3 is 18 mF cm −2 , larger than RAG2 and RAG4 (Figure S11).…”

“…OER and hydrogen evolution reaction (HER) are the two half‐reaction of water splitting. However, the overpotential requirement of both OER and HER has severely limited the energy utilization efficiency of water splitting –,, Some efficient strategies have been applied to HER in acid media or even in alkaline media with a low overpotential,, while OER still requires a high overpotential,–, comparatively.…”

Construction of surface lattice oxygen in metallic N−CuCoS1.97 porous nanowire for wearable Zn−air battery

“…The energy conversion performance of those catalysts was confirmed using homemade Zn −air battery as a model [59][60][61][62][63][64] . The battery was built using zinc plate as the anode, catalysts as the air −cathode, and 6.0 M KOH as the electrolyte.…”
