Metal - organic frameworks derived Ni5P4/NC@CoFeP/NC composites for highly efficient oxygen evolution reaction

Fe-Based Metal Organic Framework-Derived FeNiP/N-Doped Carbon Heterogeneous Core–Shell Structures for Oxygen Evolution

“…52 FeNiP or FeNi LDH/MOF grows on the surface of the nanocube and covers part of the pores, reducing the surface area. 53 In the ECSA-normalized LSV curves (Figure S9), FeNiP/NC has the lowest initial overpotential in the process of the OER, further revealing its superior intrinsic catalytic activity.…”

“…However, the C dl of FeNiP/NC and FeNi LDH/MOF is smaller than that of Fe-soc-MOF (2.2 mF/cm 2 ), which may be ascribed to the covering effect . FeNiP or FeNi LDH/MOF grows on the surface of the nanocube and covers part of the pores, reducing the surface area . In the ECSA-normalized LSV curves (Figure S9), FeNiP/NC has the lowest initial overpotential in the process of the OER, further revealing its superior intrinsic catalytic activity.…”

“…FeNiP/NC exhibits excellent OER performance and stability than most nearly reported transition metal phosphide electrocatalysts in alkaline solution (Figures S10 and S11 and Table S1). ,,,,,,− Excellent catalytic performance can be attributed to the ordered core–shell structure. N-doped porous carbon core improves the electrical conductivity, facilitates mass and charge transfer, and provides internal support to enhance the stability of the material.…”

Constructing interface engineering and tailoring a nanoflower-like FeP/CoP heterostructure for enhanced oxygen evolution reaction

“…This abnormal phenomenon may have been derived from the synergistic action of bimetal and the change of electron density around Co and P centers because of the introduction of Fe regulating the electronic structure of the catalyst. [66][67][68] The inuence of phosphating temperature on ECSA is also discussed and the corresponding C dl values are shown in Fig. 5b.…”

Hierarchical porous NiFe-P@NC as an efficient electrocatalyst for alkaline hydrogen production and seawater electrolysis at high current density

“…[41][42][43] Meanwhile, it has been demonstrated that multi-metallic phosphides possess higher catalytic properties than monometallic phosphides and boost HER activity further. [44][45][46] However, most metal phosphides exhibit unsatisfactory catalytic performance because of the insufficient number of active sites and instability. In view of this point, it is necessary to design a catalyst with a unique structural framework, surface topography and large specific surface area to expose active sites to ultimately improve the catalytic performance.…”
