Carbon plays a critical role in enhancing the electrochemical activity and stability of catalysts. In this study, a cost-effective method for synthesizing crystalline carbon-wrapped iron nitride (CW@Fe₂N) nanoparticles (NPs) is presented, showcasing their exceptional bifunctional electrocatalytic performance for the hydrogen evolution reaction (HER), oxygen evolution reaction (OER), and overall water splitting. The CW@Fe₂N NPs were thoroughly characterized to analyze their morphology, crystal structure, chemical composition, and surface properties, revealing a robust core-shell structure with carbon encapsulation. This crystalline carbon layer not only enhances catalytic activity but also improves the stability of the nanoparticles under electrochemical conditions. To benchmark performance, carbon-wrapped iron nanoparticles (CW@Fe NPs) were also synthesized and tested. Electrochemical analysis in alkaline media demonstrated the superior bifunctional electrocatalytic activity of CW@Fe₂N NPs, achieving current densities of 10 mA cm⁻² at overpotentials of 205 mV for OER and 94 mV for HER. The outstanding performance is attributed to the synergistic interaction between iron nitride and the crystalline carbon shell, which facilitates charge transfer and provides structural integrity. Additionally, the CW@Fe₂N catalyst exhibited excellent energy efficiency in a two-electrode system, maintaining a current density of 10 mA cm⁻² with a cell voltage of just 1.567 V. These findings highlight the potential of CW@Fe₂N NPs as scalable and highly effective electrocatalysts for sustainable hydrogen production through water splitting.</div></div>","PeriodicalId":11266,"journal":{"name":"Diamond and Related Materials","volume":"156 ","pages":"Article 112414"},"PeriodicalIF":4.3,"publicationDate":"2025-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143923409","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Barley bran, as a raw material, is distinguished by its high carbon content and the presence of chemical compounds such as polysaccharides, proteins, fatty acids, and triglycerides, which contribute to the significant presence of oxygen atoms. The BB material was characterized using techniques such as Roentgen diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), dry weight analysis, scanning electron microscopy with energy dispersive spectroscopy (SEM-EDS), and CHNOS elemental analysis. The results of XRD and FT-IR analysis were compared with those for dried CQDs, which show significant structural changes. Transmission Electron Microscopy (TEM) was used to analyze the size and structure of CQDs. The particles with a crystalline structure were characterized by an average size of 5.5 nm and a distance between crystal planes in the range of 0.19–0.28 nm. The optical properties of the CQDs particles were checked by UV–Vis spectroscopy analysis and their ability to emit light by spectrofluorimetry. The suspensions were characterized by absorption at 280 nm and fluorescence at 380 nm excitation with an emission peak base of about 200 nm and a peak maximum of 464 nm. The analysis showed that process parameters such as temperature, synthesis time, and filtrate volume significantly affect the properties of the obtained CQDs. The best fluorescence results were obtained for samples synthesized at 235 °C or 250 °C with larger filtrate volumes. Analysis of the optimization of the synthesis process showed that the best optical properties were obtained for samples prepared at 250 °C for 1 h from a filtrate volume of 40 mL.

In this study, we investigate the thermal properties of noble metal-decorated graphene nanoplatelet-reinforced Cu composites (Au-GNP/Cu, Ag-GNP/Cu, and Ag-N-GNP/Cu) with optimized porosity (i.e., lowest and highest), building on our previous work on their physical and mechanical properties. The thermal performance of these composites as heat sinks for LED lights was compared to undecorated GNP/Cu, sintered Cu, and commercial Cu. Decorated GNP/Cu composites exhibited enhanced thermal conductivity over undecorated GNP/Cu and sintered Cu, though values remained below commercial Cu due to porosity. High-porosity samples demonstrated superior cooling, with 0.1-Ag-GNP/Cu (22.94 % porosity) reducing LED operating temperatures by 15.83 % compared to sintered Cu. Sintered Cu (18.64 % porosity) also outperformed commercial Cu (0.11 % porosity), lowering LED temperatures by 8.57 %, highlighting the role of porosity in convective heat transfer. LED Luminous efficiency remained above 90 % for all composites, peaking at 97.21 % for 0.1-Ag-GNP/Cu.

The hybrid composite takes advantage of the high surface area, enhanced electronic conductivity and active sites introduced by NSBC to overcome the constraints of bare NiHCF, including the rapid recombination of charges and the restricted absorption of visible light. The composite's structural integrity, chemical interaction and synergistic properties were verified through a comprehensive characterization such as X-ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscopy (SEM) techniques. The NiHCF/NSBC composite demonstrated an increased surface area (176 m²/g) and diminished photoluminescence intensity in comparison to pristine NiHCF and NSBC, indicating higher pollutant adsorption and lower charge recombination. The photocatalytic degradation results demonstrated that NiHCF and NSBC were substantially outperformed, which demonstrated remarkable degradation efficiencies of 94 % for CIP and 92 % for AMX under visible light within 90 min.
