Sustainable Carbon‐Based Catalyst Materials Derived From Lignocellulosic Biomass for Energy Storage and Conversion: Atomic Modulation and Properties Improvement

Carbon Energy, Journal Year: 2025, Volume and Issue: unknown

Published: March 20, 2025

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.
