“…The electrochemical performance of LSBs has been effectively enhanced by the development of carbon-based materials with high specific surface areas and porosity to serve as sulfur host cathodes, , such as carbon nanotubes, − graphene, − graphene oxide, − and porous carbon. − Although the latter have attracted much research attention due to their ability to restrict the diffusion of LiPSs, their physical interaction is still insufficient to inhibit the shuttle effect. , This can be attributed to weak van der Waals forces between polar LiPSs and non-polar carbon materials and limited numbers of active sites in pure carbon materials. Highly electronegative heteroatoms, such as O, N, S, and P, have been introduced into carbon matrices to enhance the polarity and sulfophilicity of carbon skeletons with the purpose of improving the adsorption of polar LiPSs on non-polar carbon materials. − Although the development of these heteroatom-doped carbon-based sulfur hosts has progressed well, their performance needs to be further improved to meet the stringent requirements set by LSB commercialization targets.…”

Effective fabrication of electrocatalysts active in anchoring and converting lithium polysulfides is critical for the manufacturing of high-performance lithium–sulfur batteries (LSBs). In this study, original Fe3O4 nanospheres with diameters close to 12 nm were finely dispersed over a porous nitrogen-doped carbon matrix by the freeze-drying method to produce a three-dimensional composite material (nano-Fe3O4/PNC) suitable for application as a sulfur host in LSBs. Nano-Fe3O4/PNC loaded with sulfur (S@nano-Fe3O4/PNC) was used as a cathode in a Li–S cell, whose initial discharge specific capacity reached 1256 mA h g–1 at a 0.1 C rate. After 100 charge–discharge cycles at a 0.2 C rate, the reversible capacity of S@nano-Fe3O4/PNC remained at 745 mA h g–1, demonstrating a capacity retention rate of 70%. Importantly, a high Coulombic efficiency of more than 99% was achieved, indicating effective inhibition of the polysulfides’ “shuttle effect” by nano-Fe3O4/PNC. The use of electrolytes containing lithium nitrate further reduces the “shuttle effect” of polysulfides. This study demonstrates the synergistic effect between metal oxide nanoparticles and N-doped carbon, which plays an important role in promoting the adsorption and conversion of polysulfides in LSBs.

“…In this process, the Ni and Co ions within the hollow framework were gradually transformed into uniform nickel and cobalt nanoparticles while the BTC were in situ carbonized/formatted to porous carbon hollow microspheres. With the gradual increase of the calcination temperature, the nitrogen-doped carbon nanotubes are gradually extruded from the hollow carbon spheres under the catalysis of the metal nickel and cobalt nanocrystals. ,− As shown in the XRD pattern of Ni 1.4 Co 0.6 /NCNHMs (Figure S2), three sharp peaks appear at 44.38°, 51.72°, and 76.15° between those of Ni (JCPDS No. 04-0850) and Co (JCPDS No.…”

Electrocatalytic water splitting (EWS) is a key technology for generating clean and sustainable hydrogen, which can store abundant energy but is impeded by the insufficient efficiency of the anode and cathode catalyst. Designing and constructing non-noble metal composite bifunctional electrocatalysts for promoting both the cathodic hydrogen evolution (HER) and anodic oxygen evolution reactions (OER) is clearly of great importance for EWS. Thus, the chemical composition and morphology of cobalt−nickel bimetal phosphide (Ni, Co) 2 P nanoparticles (NPs) encapsulated in nitrogen-doped carbon nanotube hollow microspheres (NCNHMs) can regulate the redox-active sites and enhance the electron transfer, resulting in superior splitting efficiency. Contributing to the synergistic effects between highly active Co−Ni bimetal phosphide NPs and NCNHMs, the obtained Co−Ni bimetal phosphide/NCNHMs display remarkable electrochemical performance for water splitting compared with Ni 2 P/NCNHMs. Therefore, the Ni 1.4 Co 0.6 P/NCNHMs catalysts achieved through a nitriding−phosphidation strategy derived from a hollow Ni 1.4 -Co 0.6 -based metal organic framework (MOF) exhibit superior HER catalytic activity (87.9 mV at 10 mA cm −2 tested in 0.5 M H 2 SO 4 and 64.4 mV at 10 mA cm −2 tested in 1 M KOH) and OER catalytic activity (320.0 mV at 10 mA cm −2 tested in 1 M KOH). The Ni 1.4 Co 0.6 P/NCNHMs deliver excellent water-splitting catalytic activity (1.55 V at 10 mA cm −2 tested in 1 M KOH), which is competitive with that of current non-noble metal electrocatalysts. Density functional theory (DFT) simulations and related experimental results suggest that the electron transfer from Co doping and coating with NCNHMs improves the electronic states, which would enhance the binding strength with H-bonds and then promote the electrocatalytic activity.
