Abstract Nitrate electroreduction is promising for achieving effluent waste‐water treatment and ammonia production with respect to the global nitrogen balance. However, due impeded hydrogenation process, high overpotentials need be surmounted during nitrate electroreduction, causing intensive energy consumption. Herein, a hydroxide regulation strategy developed optimize interfacial H 2 O behavior accelerating conversion of at ultralow overpotentials. The well‐designed Ru─Ni(OH) electrocatalyst shows remarkable efficiency 44.6% +0.1 V versus RHE nearly 100% Faradaic NH 3 synthesis 0 RHE. In situ characterizations theoretical calculations indicate that Ni(OH) can regulate structure promoted dissociation process contribute spontaneous hydrogen spillover boosting NO − Ru sites. Furthermore, assembled rechargeable Zn‐NO /ethanol battery system exhibits an outstanding long‐term cycling stability charge–discharge tests high‐value‐added ammonium acetate, showing great potential simultaneously removal, conversion, chemical synthesis. This work not only provide guidance in extensive reactions but also inspire design novel hybrid flow multiple functions.

Abstract The oxidative degradation of plastics in conjunction with the production clean hydrogen (H 2 ) represents a significant challenge. Herein, Ni 3 S 4 /ZnCdS heterojunction is rationally synthesized and employed for efficient H high‐selectivity value‐added chemicals from waste plastic. By integrating spectroscopic analysis techniques density functional theory (DFT) calculations, solely electron transfer‐mediated reaction mechanism confirmed, wherein extracts electrons ZnCdS (ZCS) to promote spatial segregation photogenerated holes, which not only facilitates but also maintains high oxidation potential holes on ZCS surface, favoring hole‐dominated plastic oxidation. Notably, catalyst exhibited rates as 27.9 17.4 mmol g −1 h , along selectivity 94.2% 78.3% liquid product toward pyruvate acetate polylactic acid (PLA) polyethylene terephthalate (PET), respectively. Additionally, carbon yields 26.5% 2.2% are measured after 9 photoreforming, representing highest values reported date. Overall, this research presents promising approach converting into fuel valuable chemical products, offering solution growing issue “ White Pollution ”.

To surmount the shortcomings of powder-based catalysts and small electrode sizes, development meter-scale integrated materials is essential for practical electrocatalytic applications, which requires fine control over effective surface grafting catalytic active sites on large-size electrodes as well addressing challenge balancing cost-effective large-scale manufacturing with highly stable operation. Herein, we report a low-cost, facile, scalable method directly constructing single-molecule-integrated using commercially available, flexible, size-tailored conductive carbon textiles (e.g., graphite felt) well-defined planar conjugated molecules metallophthalocyanines) via heterostacking steered cross-scale heterointerfacial assembly. This universal unlocks limitations traditional approaches that involve integrating catalysts, particles, binders Nafion), supported paper) through multiple processing steps typically result in centimeter-level electrodes. Meaningfully, our enables precise size, composition, microenvironment, structure to match various environments.

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.
