Deep eutectic solvents (DESs) have shown remarkable efficiency in the oxidation of HMF as a sustainable solvent. These solvents not only enhance solubilization but also activate biomass-derived hydroxyl compounds via hydrogen bonds reconstruction. This study leverages the architecture and functionality of natural enzymes and coenzymes in the respiratory chain system to develop a unique biomimetic catalytic system. In this system, HMF is oxidized to FDCA in imidazole-based DESs with polyoxometalates as catalyst and para-benzoquinone as electron transfer mediators. The findings demonstrate that the adjustment of hydrogen bond acceptor (HBA) or hydrogen bond donor (HBD) enables precise control over the hydrogen bond strength in DESs, thereby accurately regulating the distribution of HMF oxidation products. Furthermore, the optimization of hydrogen bond strength can also activate the OH bond in HMF, consequently expediting the oxidation reaction. The cyclic voltammetry measurements provide compelling evidence of dioxygen activation and efficient electron transferring in a biomimetic catalytic system, resulting in a remarkable 21-fold increase in current density. This research not only advances utilization and development of biomass resources but also offers novel perspectives into constructing efficient catalytic oxidation systems.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e2402589"},"PeriodicalIF":7.5,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143661712","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ammonia electrooxidation reaction (AmOR) emerges as a promising avenue to leverage NH₃ in energy conversion and environmental applications. This review explores the multifaceted importance of NH3 oxidation through three primary strategies: its integration into fuel cell technology for clean energy generation, its use in wastewater treatment for ammonia removal, and its application in electrolyzer setups for producing value-added products. Special emphasis is placed on oxidizing NH3 to nitrite (NO2 -) and nitrate (NO3 -) in electrolyzers as a potential alternative to the energy-intensive Ostwald process. The review highlights recent advances in catalyst development for efficient NO2 -/NO3 - synthesis, the influence of the pH on reaction selectivity, and various reported experimental AmOR solutions. By addressing these critical aspects, this work aims to underscore the potential of NH3 oxidation in electrolyzers for sustainable energy solutions.

However, the presence of toxic heavy metal ions remains a significant challenge for eco-friendly material development. Here, we introduce the design and fabrication of a quantum-dot-in-vitrimer (QD@vitrimer) nanocomposite that leverages dynamic covalent bonds, providing chemical extractability of the embedded QDs from crosslinked polymers. Unlike commercially available UV-cured resins, our QD@vitrimer nanocomposite demonstrates uniform QD dispersion with minimal aggregation, as confirmed by synchrotron transmission small-angle X-ray scattering and high-resolution scanning transmission electron microscopy. The composites can be degraded via an alcoholysis process driven by built-in catalysts, enabling rapid breakdown and efficient QD extraction under neutral conditions. We achieved 99.9% QD extraction efficiency while preserving the crystal structure and photoluminescence quantum yield of the QDs, significantly enhancing the reusability of these valuable nanomaterials, as verified by inductively coupled plasma optical emission spectrometry and synchrotron X-ray absorption spectroscopy. Finally, we re-fabricated the QD@vitrimer nanocomposite using the recycled QDs, establishing a closed-loop system that extends the material's lifecycle.

High-polarity functional groups are commonly incorporated into CIMs designs to improve interfacial contact with the active layer and mitigate the power loss at metal electrodes. Herein, we report a hydrogen-bonding interfacial material, hydroxyethylamine-functionalized perylene diimide (PDIN-OH), which further reduces the cathode work function while maintaining excellent interfacial contact with the active layer. The outstanding conductivity of PDIN-OH, combined with its doping interaction with acceptor materials, significantly enhances its tolerance to thick films. In binary OSCs using the classical active layers PM6:Y6 and D18:L8-BO, devices incorporating PDIN-OH achieved remarkable power conversion efficiencies (PCEs) of 17.51 % and 19.36 %, respectively, along with outstanding stability.

The use of a PCET mediator based on a Zr coordination cage enabled formation of NH3 under visible light irradiation (440 nm). Importantly, the incorporation of Li+ as a Lewis acid within the cage structure further generated highly reactive sites that pre-associate and activate NO3 -, enhancing the catalytic activity.

Specifically, at a current density of 200 mA cm-2, Cu/SiO2-10 including majority of CuSiO3 facilitates the selective reduction of CO2 to CH4 with a high Faradaic ratio of CH4/C2H4 (7.2/1), whereas Cu/SiO2-50 primarily consisting of CuO exhibits a higher Faradaic ratio of C2H4/CH4 (17.9/1).

In-situ infrared spectroscopic and CO-TPD characterization further revealed that CuSiO3 has a stronger protonation capacity and promotes the direct protonation of adsorbed *CO species to CH4, while Cu0/Cu+ is more conducive to the C-C coupling between the intermediate species *CHO with adsorbed *CO species to form C2H4 due to the stronger CO adsorption capacity and higher coverage.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202402461"},"PeriodicalIF":7.5,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143655758","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
