The electrochemical synthesis of ammonia is highly dependent on the coupling reaction between nitrate and water, for which an electrocatalyst with a multifunctional interface anticipated to promote deoxygenation hydrogenation water. Herein, by engineering surface bimetallic Ni/Co-MOFs (NiCoBDC) hydrogen-substituted graphdiyne (HsGDY), hybrid nanoarray NiCoBDC@HsGDY has been achieved toward scale-up nitrate-to-ammonia conversion. On one hand, partial electron transfers from Ni2+ coordinatively unsaturated Co2+ NiCoBDC, not only promotes *NO3 but also activates water-dissociation *H Ni2+. other conformal coated HsGDY facilitates both electrons NO3- ions gathering NiCoBDC HsGDY, moves forward rate-determining step *N *H2O Co2+. As result, such delivers high NH3 yield rates Faradaic efficiency above 90% over wide potential pH windows. When assembled into galvanic Zn-NO3- battery, power density 3.66 mW cm-2 achieved, suggesting its in area aqueous Zn-based batteries.

One-dimensional fiber architecture serves as an excellent catalyst support. The orderly arrangement of active materials on such a substrate can enhance catalytic performance by exposing more sites and facilitating mass diffusion; however, this remains challenge. We developed interfacial assembly strategy for the distribution metal nanocrystals different substrates to optimize their electrocatalytic performance. Using electrochemical nitrate reduction reaction (NO3- RR) representative reaction, iron-based nanofibers (Fe/NFs) structure achieved removal capacity 2317 mg N/g Fe N2 selectivity up 97.2 %. This could promote rational design synthesis fiber-based electrocatalysts.

Abstract The electrochemical nitrate reduction reaction (NO 3 RR) holds promise for ecofriendly removal. However, the challenge of achieving high selectivity and efficiency in electrocatalyst systems still significantly hampers mechanism understanding large‐scale application. Tandem catalysts, comprising multiple catalytic components working synergistically, offer promising potential improving NO RR. This review highlights recent progress designing tandem catalysts RR, including noble metal‐related system, transition metal electrocatalysts, pulsed electrocatalysis strategies. Specifically, optimization active sites, interface engineering, synergistic effects between catalyst components, various situ technologies, theory simulations are discussed detail. Challenges opportunities development scaling up RR further discussed, such as stability, durability, mechanisms. By outlining possible solutions future design, this aims to open avenues efficient comprehensive insights into mechanisms energy sustainability environmental safety.

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.
