Abstract

Recent advances in cobalt phosphide-based materials for H2 generation and electrochemical energy storage are systematically reviewed.

Empowering Metal Phosphides Anode with Catalytic Attribute toward Superior Cyclability for Lithium‐Ion Storage

“…These data imply that the good stability of the N‐C might also help to stabilize the supported Ni 2 P nanoparticles for long‐term cycling, apart from the catalysis of the N‐C material. Remarkably, the cycling life and stability for the Li‐ion storage demonstrated in this work reach the highest record compared with reported state‐of‐the‐art MP‐based anodes (Figure e) . Apart from the catalysis of the N‐C materials, the in situ formation of Ni (Figure S9c, Supporting Information) might also help in the decomposition of Li 3 P suggested by the DFT calculation (Figure S10, Supporting Information).…”

“…d) Long‐term cycling performance of N‐C, Ni 2 P@N‐C, and Ni 2 P electrodes at a current rate of 1 A g −1 . e) The cycle life and stability of this work are compared with other reported works: Ni 2 P⊂pGN, Ni 2 P/G, h‐Ni 2 P, MoP‐C, CoP/NC, (Fe) Ni 2 P/G, CuP 2 /C, Sn 4 P 3 /C, Ni 12 P 5 /CNTs, Ni 2 P/C, Sn 4 P 3 /G, CoP⊂NPPCS, H‐FeP@C@GR, GeP 5 @C‐NF, CuP 2 /C, Co 2 P/NCNTFs, and Ni 2 P/NPC …”

Synthesis of Ni4.5Fe4.5S8/Ni3S2 film on Ni3Fe alloy foam as an excellent electrocatalyst for the oxygen evolution reaction

“…The energy crisis and environmental issues are critical challenges, due to limitations of fossil fuels and population growth. [1][2][3][4][5] In order to deal with these problems, research on new energy sources is necessary. New energy sources such as solar and wind energies are highly promising alternatives, but their use is limited by their intermittencies and geographically uneven distributions.…”

Carbon‐Enriched Cobalt Phosphide with Assorted Nanostructure as a Multifunctional Electrode for Energy Conversion and Storage Devices

“…It is well known that the cobalt‐based compounds have been extensively used in various electrochemical and electrocatalytic applications especially supercapacitors, sodium‐ion batteries, a zinc‐air battery, water electrolyzers and fuel cells due to its appealing dualistic reversible redox couples and extreme strength in high alkaline electrolytes . Among these, the cobalt phosphide has emerged itself as an impressive material than the oxides and sulphides . Phosphides with its metalloid property combine with cobalt resembling a submetallic alloy, which possesses much higher intrinsic conductivity that induces bouncing kinetic rate overpowering the oxides.…”

“…Conferring to conversion systems, CoP based electrode materials are employed predominantly as an effective electrocatalyst in the much‐anticipated water splitting systems ,. The water splitting system gives the impression to be a sensational renewable and clean energy resources to replace the use of limited fossil fuels .…”
