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

Carbon Energy, Год журнала: 2025, Номер unknown

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.

Microwave-assisted exploration of the electron configuration-dependent electrocatalytic urea oxidation activity of 2D porous NiCo2O4 spinel

Journal of Energy Chemistry, Год журнала: 2023, Номер 91, С. 226 - 235

Опубликована: Дек. 28, 2023

Urea holds promise as an alternative water-oxidation substrate in electrolytic cells. High-valence nickel-based spinel, especially after heteroatom doping, excels urea oxidation reactions (UOR). However, traditional spinel synthesis methods with prolonged high-temperature lack kinetic precision, hindering the balance between controlled doping and highly active two-dimensional (2D) porous structures design. This significantly impedes identification of electron configuration-dependent sites doped 2D spinels. Herein, we present a microwave shock method for preparation NiCo2O4 spinel. Utilizing transient on-off property pulses precise structural design, non-metal (boron, phosphorus, sulfur) distinct extranuclear disparities serves straightforward examples investigation. Precise tuning lattice parameter reveals impact covalent bond strength on stability. The introduced defect levels induce unpaired d-electrons transition metals, enhancing adsorption electron-donating amino groups molecules. Simultaneously, Bode plots confirm mechanism rapid migration caused by reduced band gaps UOR activity. prepared phosphorus-doped NiCo2O4, optimal configuration control, outperforms most reported modification strategy advances understanding theoretical structure-activity mechanisms high-performance spinels UOR.
