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 availability of robust and accessible active sites in iron–nitrogen-carbon (Fe–Nx-C) electrocatalysts is essential to optimize the oxygen reduction reaction (ORR), which main obstacle commercial realization fuel cells. Herein, a modified hard templating method develop efficient Fe–Nx-C has been presented that not only ensured generation porous architecture but also helped homogeneous distribution Fe throughout structure. First, silica nanoparticles (NPs) were grown via Stöber process then functionalized atomically with iron through two different types silane chains, i.e., (3-aminopropyl)triethoxysilane (APTES) N-(2-Aminoethyl)-3-aminopropyltriethoxysilane (EDTMS). Fe-functionalized simultaneously acting as sacrificial template well an source was impregnated nicarbazin, carbon nitrogen precursor. dried mix subject pyrolysis (H1) followed by acid washing dissolve templates, then, again, it subjected another treatment (H2). At each proceeding step, ORR activity both acidic alkaline media improved samples obtained at last stage (i.e., H2) outperformed other counterparts collected initial stages fabrication pathway. Eventually, electrocatalyst developed using EDTMS-type attached NPs (E_FeNC_H2) demonstrated highest onset potentials 990 mV vs RHE 862 media. Moreover, lower peroxide yield E_FeNC_H2 signifying nearly direct 4e– attributed specific surface area (627 m2 g–1) optimum combination moieties dispersed carbonaceous framework.

Metal-organic frameworks (MOFs) are promising precursors for creating metal-nitrogen-carbon (M-N-C) electrocatalysts with high performance, though maintaining their structure during pyrolysis is challenging. This study examines the transformation of a Zn-based MOF into an M-N-C electrocatalyst, focusing on preservation carbon framework and prevention Zn aggregation pyrolysis. A highly porous Zn-N-C electrocatalyst derived from Zn-TAL (where TAL stands TalTech-UniTartu Alliance Laboratory) was synthesized via optimized pyrolysis, yielding notable electrocatalytic activity toward oxygen reduction reaction (ORR). Scanning electron microscopy (SEM) X-ray diffraction spectroscopy (XRD) analyses confirmed that preserved its integrity remained free metal aggregates, even at elevated temperatures. Rotating disc electrode (RDE) tests in alkaline solution showed demonstrated ORR par commercial Pt/C electrocatalysts. In anion-exchange membrane fuel cell (AEMFC), material pyrolyzed 1000 °C exhibited peak power density 553 mW cm-2 60 °C. work demonstrates excellent precursor forming hollow structures, making it high-performance Pt-free cells.
