FA achieves uniform zinc deposition and better low temperature performance of AZIBs by participating in Zn²⁺ solvation structure, interaction with H₂O in electrolyte, preferentially adsorping on Zn surface, and promoting the formation of SEI.

The hydrogel-supported CN photocatalyst for H₂ evolution frees itself from an aqueous suspension by using the water stored in hydrogels.

The multiple ordered porous honeycomb structure of g-C ₃ N ₄ with carbon ring in-plane splicing (C _r –PHCN) has been successfully fabricated with simultaneous morphology regulation and electronic structure modulation.

A novel ferroelectric photocatalyst modulated by the surface and polarization states is developed to promote the CO ₂ reduction reaction, and the lattice distortion and elemental coordination environment are elaborated in detail.
