“…This negative shi phenomenon may be caused by an initial state effect, for example, charge transfer from a metal to a carrier, due to the small particle size, lattice strain, and many atoms having electron defects. 33,46 To prove the universality of our synthesized strategy, a series of binary Pt-M (M ¼ Fe, Co, Ni) and ternary Pt-Cu-Fe nanoalloys were deposited on a carbon support (vxc72), and were noted as Pt-Cu-vxc72, Pt-Co-vxc72, Pt-Ni-vxc72, Pt-Fe-vxc72, and Pt-Cu-Fe-vxc72.

“…Recently, metal carbides are emerging as a promising electrocatalyst in water splitting, due to the crystal defect structures, the outstanding H* adsorption ability, the high stability and the low cost. [ 139,140,145 ] Lin et al [ 140 ] synthesized Fe 3 C‐Mo 2 C/nitrogen‐doped carbon heteronanofibers (Fe 3 C‐Mo 2 C/NC HNFs) via an electrospun method followed by pyrolysis process ( Figure a). As shown in Figure 16b, the obvious heterointerface between Fe 3 C and Mo 3 C phases could be observed.…”

Electrochemical water splitting, as a promising sustainable‐energy technology, has been limited by its slow kinetics and large overpotential. This shortcoming necessitates the design of 1D nanocatalysts with large surface area, high electronic conductivity, and easily tunable composition. Herein, recent progress about electrocatalytic water splitting based on the advanced electrospun nanomaterials is reviewed. First, the related fundamentals of electrochemical water splitting according to two main aspects are discussed as follows: hydrogen evolution reaction and oxygen evolution reaction. Second, the structure design and the electrocatalytic properties of electrospun nanomaterials according to difference in component (including single metal‐based electrocatalysts, metal alloy‐based electrocatalysts, metal oxide‐based electrocatalysts, metal sulfide‐based electrocatalysts, metal phosphide‐based electrocatalysts, metal carbide‐based electrocatalysts, etc.) are summarized. Finally, the future perspectives and challenges for designing next‐generation 1D electrospun nanocatalysts for electrochemical water splitting are concluded.

“…Bi‐ or multimetal nanomaterials have been regarded as a new typical attractive topic for HER application. The construction of bi‐ or multimetal nanoparticles to form a hybrid or alloy can be beneficial for the efficient charge transfer capability and exposure of more active sites, which is favorable for the enhanced HER activity 67‐71 . For example, ultrasmall PtCu alloy nanoparticles embedded in CNFs were prepared via an electrospinning and graphitization process, delivering a low overpotential of 71 mV at 10 mA cm −2 with a small Tafel slope of 68 mV dec −1 and exchange current density of 0.863 mA cm −2 67 .…”

Nowdays, electrocatalytic water splitting has been regarded as one of the most efficient means to approach the urgent energy crisis and environmental issues. However, to speed up the electrocatalytic conversion efficiency of their half reactions including hydrogen evolution reaction (HER) and oxygen evolution reaction (OER), electrocatalysts are usually essential to reduce their kinetic energy barriers. Electrospun nanomaterials possess a unique one‐dimensional structure for outstanding electron and mass transportation, large specific surface area, and the possibilities of flexibility with the porous feature, which are good candidates as efficient electrocatalysts for water splitting. In this review, we focus on the recent research progress on the electrospun nanomaterials‐based electrocatalysts for HER, OER, and overall water splitting reaction. Specifically, the insights of the influence of the electronic modulation and interface engineering of these electrocatalysts on their electrocatalytic activities will be deeply discussed and highlighted. Furthermore, the challenges and development opportunities of the electrospun nanomaterials‐based electrocatalysts for water splitting are featured. Based on the achievements of the significantly enhanced performance from the electronic modulation and interface engineering of these electrocatalysts, full utilization of these materials for practical energy conversion is anticipated.
