Recent Advances in 1D Electrospun Nanocatalysts for Electrochemical Water Splitting

“…Therefore, researches should be focused on how to precisely tailor and preserve such structures and further explore more unique and fresh electrospun nanostructure. [ 21,159 ] 3) Metal oxides as the most reported fibrous nanocatalyst, their various nanostructures can be exploited to provide rich defects, plentiful inner voids, abundant active sites, and multiphase heterogeneous interfaces. Metal oxides are still a promising direction worthy of being expanded and further explored, especially related mechanism with focusing on maximizing the synergistic effect between various structures and CNFs.…”

“…Therefore, the low conductivity, chemical structure instability, volume expansion, and sluggish kinetics of active phases are impressive challenges and are expected to be resolved in this research area. [ 21 ] 6) Most researches on water splitting of electrospun nanocatalysts have focused on the design of single‐functional catalysts, especially OER direction. However, the ambiguous related mechanism of OER has restricted the further development of electrocatalysts in water splitting.…”

“…Currently, various approaches have been adopted to fabricate the 1D nanomaterials with different morphologies, such as sacrificial template method, hydrothermal/solvothermal method, sol–gel method, chemical vapor deposition, self‐assembly, electrochemical anodization, electrospun technique, etc. [ 16–21 ] Notably, electrospinning technology has become a promising method for preparing diverse structures of 1D nanofibers by changing the nozzle structures, and controlling the experiment conditions. For example, the solid nanofibers were easily fabricated by traditional single‐nozzle electrospinning, including metal compound/carbon nanofibers and carbon‐free nanofibers.…”

The Role of Electrospun Nanomaterials in the Future of Energy and Environment

“…Tunable surface area, pore size, thickness, and their potential for incorporation of active redox or pseudocapacitive materials—such as redox metal centers, metal oxides, metal sulfides, conducting polymers, etc.—have offered solutions for development of light-weight supercapacitors with high capacitance and low resistance [ 117 , 118 ]. In a comprehensive review, Liang et al studied recent advancements in carbon nanofibers, carbon nanofiber-based composites, and transition metal oxide fibers as electrode materials in supercapacitors [ 118 ]. For instance, electrochemical performance of carbon nanofibers was improved as supercapacitor electrode materials by incorporating Fe 1−x S-TiO 2 nanoparticles into fibers.…”

“…The filter was made adopting the polyethylene terephthalate (PET) for the outer layer deposition and the polivinilidenfluoruro (PVDF) for the nanomembrane inner layer, developed via electrospinning [ 30 ] (dimensions 1460 × 2031 × 1435 mm). This latter technology offers a higher resolution and great advantages in material processing over a wide range of applications, such as biosensors [ 31 ], tissue engineering [ 32 , 33 ], drug delivery [ 34 ], and supercapacitors [ 35 ].…”
