ABSTRACT Carbon electrocatalyst materials based on lignocellulosic biomass with multi‐components, various dimensions, high carbon content, and hierarchical morphology structures have gained great popularity in electrocatalytic applications recently. Due to the catalytic deficiency of neutral atoms, usage single lignocellulosic‐based electrocatalysis involving energy storage conversion presents unsatisfactory applicability. However, atomic‐level modulation lignocellulose‐based can optimize electronic structures, charge separation, transfer processes, so forth, which results substantially enhanced performance carbon‐based catalysts. This paper reviews recent advances rational design as electrocatalysts from an perspective, such self/external heteroatom doping metal modification. Then, through systematic discussion principles reaction mechanisms catalysts, prepared catalysts rechargeable batteries are reviewed. Finally, challenges improving prospects diverse review contributes synthesis strategy via modulation, turn promotes lignocellulose valorization for conversion.

Abstract Covalent triazine frameworks (CTFs) are promising battery electrodes owing to their designable functional groups, tunable pore sizes, and exceptional stability. However, practical use is limited because of the difficulty in establishing stable ion adsorption/desorption sites. In this study, a melt‐salt‐stripping process utilizing molten trichloro iron (FeCl 3 ) used delaminate layer‐stacked structure fluorinated covalent framework (FCTF) generate iron‐based storage active This increases interlayer spacing uniformly deposits iron‐containing materials, enhancing electron transport. The resultant melt‐FeCl ‐stripped FCTF (Fe@FCTF) shows excellent performance as potassium with high capacity 447 mAh g −1 at 0.1 A 257 1.6 good cycling Notably, molten‐salt stripping also effective improving CTF's Na + Li properties. stepwise reaction mechanism K/Na/Li chelation C═N groups proposed verified by situ X‐ray diffraction testing (XRD), ex‐situ photoelectron spectroscopy (XPS), theoretical calculations, illustrating that pyrazines coordination play main roles reacting K /Na /Li cations. These results conclude Fe@FCTF suitable anode material for potassium‐ion batteries (PIBs), sodium‐ion (SIBs), lithium‐ion (LIBs).

Lithium metal batteries (LMBs) have garnered considerable interest because of their substantial theoretical capacity. However, development is hampered due to the grave issue hazardous lithium dendrites arising from inhomogeneous (Li) electrodeposition. An effective strategy for addressing dendritic growth regulate migration behavior target molecules and/or ions during cycling. Herein, we demonstrate an in situ self-assembly where metal–organic frameworks (MOFs) grow on a polypropylene separator homogeneously along certain orientation. By integration abundant functional groups and secondary structural units, continuous, uniform, defect-free distribution MOFs substrate membrane was achieved. The intrinsic subnanochannels significantly benefit transfer Li+ restrain chaotic movement ions, resulting high number (0.86) enhanced ionic conductivity. Consequently, highly stable plating/stripping observed, leading efficacious deposition cycling over 1200 h at 2 mAh cm–2. Additionally, permselective MOF-based with tunable channel sizes promises broad applicability LMBs. Our approach paves new pathway strategies separators, which expected help develop advanced LMBs energy density long-life performance.
