Abstract 2,5‐Furandicarboxylic acid (FDCA) synthesis holds significant importance for both bio‐polymer production and emerging sustainable bio‐based alternatives environmental energy applications. Here, a metal‐free carbonaceous material—that is, biomass substrate 5‐hydroxymethylfurfural‐derived graphene‐like nitrogen doped porous carbon sheet (GNPCH)—and its application as new catalyst electrochemical FDCA is presented. The study scrutinized the catalytic principles, demonstrated surprising robustness, explored origin of high efficiency GNPCH catalyzed electro‐synthesis FDCA. Initially, facial pyrolysis 5‐hydroxymethylfurfural urea forms ultrathin with rich micropores defects. By employing GNPCH‐900 catalyst, stable, continuous operation >400 h yields Faraday efficiencies >90% achieved; those values not only represent best that are comparable to state‐of‐the‐art metal‐based counterparts, but also showcase one longest‐running reactions. A series measurements, in situ characterization, density functional theory calculations indicate mainly from pyridinic‐N‐related active sites clarify reaction pathway. These findings suggest will be potential alternative catalysts valorization.

Langmuir, Journal Year: 2024, Volume and Issue: 40(22), P. 11571 - 11581

Published: May 23, 2024

3D aerogels incorporating functionalized reduced graphene oxide (SUL/rGO) were prepared as a hydrothermal method utilizing (GO) and sulfonyldibenzene derivative (SUL) raw materials. The aromatic compound SUL, which contains hydroxyl sulfonyl groups, was bonded to (rGO) through π–π connections. obtained composite material exhibited porosity within its structure with improved hydrophilicity, along excellent electrochemical characteristics. This improvement ascribed the specific rGO structure, well pseudocapacitance inherent in both of synergistically contribute characteristics electrode Also, an analysis performed employing density functional theory from states adsorption energy SUL on surface computed further investigate charge storage process composite. SUL/rGO-2 highest capacitance value 388 F/g at current equal 1 A/g. constructed symmetrical supercapacitor, SUL/rGO-2//SUL/rGO-2, attained 14.55 Wh/kg power 350 W/kg exceptional galvanostatic charge–discharge (GCD) cyclic stability 91% following 10 000 cycles. Therefore, this review presents novel graphene-based holds promise future applications.
