“…Of course, other parameters such as the electrode's packing density, material's porosity, and morphology also varied the corresponding electrochemical performances. Nevertheless, the N,Z-MPC still shows better reversible capacity recorded at 0.05 A/g with other studies [55][56][57][58][59][60].…”

Benefiting from the additional active sites for sodium-ion (Na+) adsorption and porous architecture for electrolyte accessibility, nitrogen-doped porous carbon has been considered the alternative anode material for Na+-storage applications. In this study, nitrogen-doped and zinc-confined microporous carbon (N,Z-MPC) powders are successfully prepared by thermally pyrolyzing the polyhedral ZIF-8 nanoparticles under an argon atmosphere. Following the electrochemical measurements, the N,Z-MPC not only delivers good reversible capacity (423 mAh/g at 0.02 A/g) and comparable rate capability (104 mAh/g at 1.0 A/g) but also achieves a remarkable cyclability (capacity retention: 96.6% after 3000 cycles at 1.0 A/g). Those can be attributed to its intrinsic characteristics: (a) 67% of the disordered structure, (b) 0.38 nm of interplanar distance, (c) a great proportion of sp2-type carbon, (d) abundant microporosity, (e) 16.1% of nitrogen doping, and (f) existence of sodiophilic Zn species, synergistically enhancing the electrochemical performances. Accordingly, the findings observed here support the N,Z-MPC to be a potential anode material enabling exceptional Na+-storage abilities.

“…Obvious D and G peaks (I D /I G = 1.14) due to N‐doped carbon were confirmed in the Ni 3 Fe@NCS catalyst. [ 36 ] However, since the intensity could not be observed for the Ni 3 Fe catalyst, the absence of N‐doped carbon could be confirmed. Additionally, a metal hydroxide peak was observed in the Ni 3 Fe@NCS catalyst containing an N‐doped carbon shell, and a surface oxidation peak was detected in the Ni 3 Fe catalyst.…”

Combining an electrochemically stable material onto the surface of a catalyst can improve the durability of a transition metal catalyst, and enable the catalyst to operate stably at high current density. Herein, the contribution of the N‐doped carbon shell (NCS) to the electrochemical properties is evaluated by comparing the characteristics of the Ni3Fe@NCS catalyst with the N‐doped carbon shell, and the Ni3Fe catalyst. The synthesized Ni3Fe@NCS catalyst has a distinct overpotential difference from the Ni3Fe catalyst (ηOER = 468.8 mV, ηHER = 462.2 mV) at (200 and −200) mA cm−2 in 1 m KOH. In stability test at (10 and −10) mA cm−2, the Ni3Fe@NCS catalyst showed a stability of (95.47 and 99.6)%, while the Ni3Fe catalyst showed a stability of (72.4 and 95.9)%, respectively. In addition, the in situ X‐ray Absorption Near Edge Spectroscopy (XANES) results show that redox reaction appeared in the Ni3Fe catalyst by applying voltages of (1.7 and −0.48) V. The decomposition of nickel and iron due to the redox reaction is detected as a high ppm concentration in the Ni3Fe catalyst through Inductively Coupled Plasma Optical Emission Spectroscopy (ICP−OES) analysis. This work presents the strategy and design of a next‐generation electrochemical catalyst to improve the electrocatalytic properties and stability.

“…The nanostructured carbon materials are promising electrode materials and have been widely studied owing to their tailorable structures, which offer large active sites and reduce the path of transport for mass and charge and thus provide fast pathways for electrons in rechargeable batteries and supercapacitors [1,2]. Engineering nanostructured carbons with porous structures could further increase surface area, enhance electron transfer, and thus improve electrochemical performance.…”
