There is a lack of consideration for designing a multifunctional solid electrolyte interphase (SEI) which modifies the solvation/desolvation structure of Zn ion at the interface of Zn metal anodes.

When regulating the solvation structure of the Zn ion interface by N, S dual-doped GQDs, it also promotes its desolvation kinetics, optimizes the interfacial behavior of Zn ion deposition to prohibit Zn dendrite growth, and suppresses side reactions in the Zn anode surface.

This review stands apart from previous endeavors by offering a comprehensive overview of the strategies employed over the past decade in utilizing both electrospun and natural nanofibers as key components of proton exchange membranes and anion exchange membranes for fuel cells. Electrospun nanofibers are categorized based on their material properties into two primary groups: (1) ionomer nanofibers, inherently endowed with the ability to conduct H<sup>+</sup> (such as perfluorosulfonic acid or sulfonated poly(ether ether ketone)) or OH<sup>−</sup> (e.g., FAA-3), and (2) nonionic polymer nanofibers, comprising inert polymers like polyvinylidene difluoride, polytetrafluoroethylene, and polyacrylonitrile. Notably, the latter often necessitates surface modifications to impart ion transport channels, given their inherent proton inertness. Furthermore, this review delves into the recent progress made with three natural nanofibers derived from biodegradable cellulose—cellulose nanocrystals, cellulose nanofibers, and bacterial nanofibers—as crucial elements in polyelectrolyte membranes. The effect of the physical structure of such nanofibers on polyelectrolyte membrane properties is also briefly discussed.

To meet the substantial market demand for CFs, significant efforts have been made to develop cost-effective and sustainable CFs derived from biomass. Lignin, the most abundant polyphenolic compound in nature, is emerging as a promising precursor which is well-suited for the production of CFs due to its renewable nature, low cost, high carbon content, and aromatic structures.
