Опубликована: Март 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.

The electrochemical NO reduction reaction (NORR) toward NH3 synthesis not only helps address issues of air pollution but also holds significant energy and economic value, making it an innovative method with broad application prospects. However, designing NORR electrocatalysts that are both highly active selective remains a formidable challenge. Herein, we study the main-group p-block metal (M = Al, Ga, In)-doped C3N monolayers as promising single-atom catalysts (SACs) for through spin-polarized first-principles calculations. Our results show Al@VCC, Al@VCN, Ga@VCC, Ga@VCN systems stable exhibit metallic characteristics, ensuring effective charge transfer during process. Moreover, nitric oxide (NO) can be strongly chemisorbed activated on all four candidates adsorption free energies ranging from −0.83 to −1.59 eV then spontaneously converted into without need any applied voltage. More importantly, possesses well-suppressed ability formation H2/N2O/N2 byproducts, indicating excellent selectivity. These findings offer electrocatalyst NO-to-NH3 conversion highlight great potential metals SACs reactions.
