Oxygen evolution catalytic performance of quantum dot nickel-iron double hydroxide/reduced graphene oxide composites

Facile topochemically prepared hierarchical Ni–Fe LDH nanoflowers for the electrochemical oxygen elution reaction

“…, respectively, peaks at 532.7 and 533.6 eV assigned to adsorbed O-H of molecular H 2 O also appeared. [61][62][63] The new appearance of 529.5 eV for the Ni 5 Fe 5 -LDH is attributed to lattice oxygen of the Fe-O bond, 5 indicating the formation of iron oxide impurities.…”

Recent advances in non‐precious Ni‐based promising catalysts for water splitting application

“…This difficulty can be sorted out by designing a bimetalbased nanomaterials of high surface area, 30 the addition of conductive carbon, and reduced graphene oxide (rGO) in a layered structure. 98 The NiFe LDH@RGO composites produced by the hydrothermal method of increased surface area endowed an overpotential of 313 mV and a Tafel slope of 35.1 mV/dec at the current density of 10 mA/cm 2 . 99 Furthermore, solvothermal technique was applied to synthesize the NiFe-LDH and Ni(OH) 2 nanoplates on carbon nanotubes (CNT), which exhibited great electrocatalytic activity and stability compared with precious (Ir) catalyst, ie, onset potential of 1.45 V and TOF of 0.56 sec À1 at 300 mV overpotential in KOH.…”

“…Transition materials reveal a high overpotential, but with less conductivity and self‐aggregation, with less overpotential. This difficulty can be sorted out by designing a bimetal‐based nanomaterials of high surface area, 30 the addition of conductive carbon, and reduced graphene oxide (rGO) in a layered structure 98 . The NiFe LDH@RGO composites produced by the hydrothermal method of increased surface area endowed an overpotential of 313 mV and a Tafel slope of 35.1 mV/dec at the current density of 10 mA/cm 2 99 .…”

Self‐Supported Graphite/Graphene/NiFe‐LDH Electrodes for High Performance Oxygen Evolution Reaction

“…[ 9 ] In recent years, widely attention has been paid to the non‐noble metal layered double hydroxide (LDH) OER catalysts due to their promising catalytic performance, easy adjustment of elemental composition, and the diversity of nanostructure. [ 10 ] And many research groups have conducted in‐depth studies in this area. [ 11,12 ] Thereinto, Fe based materials have been considered to be one kinds of promising candidates, which are low cost, low environmental pollution, and abundant reserves.…”
