Density of nife
An iron–nickel alloy or nickel–iron alloy, abbreviated FeNi or NiFe, is a group of alloys consisting primarily of the elements nickel (Ni) and iron (Fe). It is the main constituent of the "iron" planetary cores and iron meteorites. In chemistry, the acronym NiFe refers to an iron–nickel catalyst or component involved in various chemical reactions, or the reactions themselves; in geology, it refers to the main constituents of telluric planetary cores (including Earth's). WebSuch NiMoSx@NiFe-LDH/NF shows excellent OER activity with a low overpotential of 297 mV to drive an industrial-level current density of 500 mA cm−2 in alkaline seawater and …

WebJan 26, 2024 · NiFe layered double hydroxide (NiFe-LDH) is a cost-effective and active catalyst for the oxygen evolution reaction (OER), yet further promoting its OER performance is an ongoing challenge. Herein, we devised a facile strategy that can form two types of Co introduced NiFe-LDH catalysts, namely CoNiFe-LDH and Co@NiFe-LDH. WebNotably, the integrated alkaline electrolyzer (with pure Ni nanowires as HER electrode) is demonstrated to reach the current density of 1000 mA cm −2 with super low voltage of 1.76 V, outperforming the state-of-the-art industrial catalysts.
Web1 day ago · The LSV curves demonstrate that Pt/D-NiFe LDH exhibits much higher current density in the whole studied potential range. Especially, 17 mV and 40 mV are required to deliver 10 and 50 mA cm −2, even surpass Pt/C (39, 91 mV for 10, 50 mA cm −2) ( Fig. 5 a and b), verifying its superior catalytic performance in alkaline seawater. WebApr 28, 2024 · According to Brunauer-Emmett-Teller (BET) model, the specific surface area (125.606 m 2 /g) of NiFe-LDH/MXene is higher than that of LDH (80.570 m 2 /g). As shown in Fig. 5b), the Barrett-Joyner-Halenda (BJH) pore size distributions (PSD) of NiFe-LDH/MXene and LDH are between 3 and 10 nm.
