Abstract For Nd2Fe14B/α-Fe nanocomposite magnets, which exhibit superior theoretical energy products, it is a great challenge to eliminate the harmful metastable phases due general fabrication during amorphous crystallization process.Here, we report strategy simultaneously and reduce grain sizes in nanocomposites by utilizing non-equilibrium laser-heated processing with ultrafast heating rates on ternary Nd(7.5+x)Fe(86.5-x)B6 (x = 0, 1.5, 4.3) alloys. In Nd9Fe85B6 alloys, rate (~ 400 ℃/s)...
A novel Zr-doping strategy was highly effective to enhance the OER activity of NiFe LDHs <italic>via</italic> accelerating charge transfer.
The development of low-cost electrocatalysts with excellent activity and durability for both the oxygen evolution reaction (OER) hydrogen (HER) poses a huge challenge in water splitting. In this study, simple scalable strategy is proposed to fabricate 3 D heteronanorods on nickel foam, which molybdenum phosphide nanorods are covered cobalt iron (P-NM-CF HNRs). As result rational design, P-NM-CF HNRs have large surface area, tightly connected interfaces, optimized electronic structures,...
The preparation of highly efficient, stable, and low-cost electrocatalysts for the oxygen evolution reaction (OER) hydrogen (HER) is still a challenge development new energy systems. In this work, NiCo bimetal loaded on porous carbon (NiCo-C/NF) grown nickel foam (NF) was obtained via pyrolysis MOF (NiCo-MOF/NF) under nitrogen atmosphere at 500 °C. Compared with NiCo-MOF/NF, NiCo-C/NF had larger specific surface uniform mesoporous structure. As an electrocatalyst in OER, type electrode...
Controlling the growth orientation of semiconductor nanowire arrays is vital importance for their applications in fields nanodevices. In present work, hexagonal CdSe with various preferential orientations have been successfully yielded by employing electrodeposition technique using porous alumina as templates (PATs). We demonstrate experimental and theoretical efforts that nanowires can be effectively manipulated varying either nanopore diameter PATs or deposited current density, which has...
