In this work, Co₃O₄ is modified by a simple sulfur-doping strategy, which   achieves a sulfur-doped Co₃O₄ (S-Co₃O₄) with significantly-enhanced  oxygen catalytic activity. The doping of sulfur promotes the exposure of cobalt active sites and brings abundant oxygen vacancies, which provide additional active sites and enhance the conductivity of Co₃O₄. Consequently, S-Co₃O₄ exhibits a low overpotential of 318 mV in the oxygen evolution reaction (OER) and an improved half-wave potential (0.788 V) for oxygen reduction reaction (ORR). In addition, the sulfur doping increases the ORR kinetic current density of pristine Co₃O₄ by a factor of 49. The assembled ZABs based on S-Co₃O₄ cathodes show a higher peak power density (98.90 mW cm⁻²) than the commercial Pt/C + RuO₂-based ZABs. This work reveals that the intrinsic oxygen catalytic activity of Co₃O₄ can be significantly strengthened by sulfur doping, which can  modify its structural characteristics and introduce structural defects.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":645,"journal":{"name":"Journal of Materials Science","volume":"60 1","pages":"355 - 366"},"PeriodicalIF":3.5,"publicationDate":"2024-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142939436","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}

Comprehensive physical and chemical characterizations of carbon blacks and Pt catalysts were performed using BET, FTIR, Raman spectroscopy, XRD, SEM, TEM, XPS (C 1<i>s</i>), ICP-MS, zeta potential, contact angle, and 3D topography analyses.

The results show that the setting difference of thermal conductivity has little influence on the simulation results, and the position of solidification welding point changes only 2.5 mm. Whether the latent heat of phase change is considered in the setting of specific heat capacity will make the position difference of solidification welding point 16 mm in the simulation results, so the equivalent specific heat capacity model should be used in the simulation. If it is necessary to qualitatively analyze the rolling section of solidified structure, the viscosity coefficient of the material in solid phase should be reasonably increased. The solid-phase line temperature should be set at the end of the fast growing phase fraction, that is, the solid-phase fraction is 0.75–0.85, and the temperature is 830 K ~ 875 K, which can make the simulation results close to the actual better.

Understanding the microstructures and formation mechanisms at the atomic scale contributes to the development of new materials with desired attributes. In this study, the precipitation behavior of a VCoNi-based medium-entropy alloy (MEA) containing Al was analyzed using aberration-corrected scanning transmission electron microscopy (STEM) technique. Our investigation revealed that the introduction of Al led to the creation of a dual-phase alloy exhibiting an Al-poor face-centered cubic phase alongside an Al-rich body-centered cubic (BCC) phase. Subsequent high-temperature annealing resulted in the precipitation of a substantial amount of lamellar hexagonal close-packed (HCP) α phase within the BCC matrix. These lamellar HCP-α phases exhibited a width of approximately 25 nm and a length of about 5 μm. Further analysis revealed that these α phases exhibited a high Ni content and a low Al content, with a notable enrichment of Ni observed at the phase boundaries. Importantly, these precipitates displayed a semi-coherent relationship with the BCC matrix, characterized by a habit plane of {2 <span>(stackrel{text{-}}{1}stackrel{text{-}}{1})</span>} and an orientation relationship of (0001)_α // (01 <span>(stackrel{text{-}}{1})</span>)_BCC and [11 <span>(stackrel{text{-}}{2})</span> 0]_α // [111]_BCC.

Equal Channel Angular Pressing (ECAP) is considered a promising technique, but results are not well addressed yet due to the complex interaction between microstructure, mechanical properties and corrosion resistance. This work is focused on this interaction through advanced metallurgical and mechanical analysis of the AZ31 alloy subjected to four successive ECAP passes at 250 °C. Dynamic recrystallization takes place during ECAP, and the microstructure has been examined by light microscopy (LM), transmission electron microscopy (TEM), electron back-scattered diffraction (EBSD) and X-ray diffraction (XRD). It exhibits a progressive decrease of grain size to 6–7 µm after 4 passes and a significant texture change leading to the alignment of basal planes to ECAP shear plane. A slight decrease in dislocation density, the refinement of Al₈Mn₅ precipitates and the increase of the fraction of high-angle grain boundaries (HAGBs) are other typical aspects highlighted by the analyses. Such complex microstructural evolution affects the mechanical properties (yield stress and hardness) and compressive residual stresses giving rise to a performance peak after the first pass. The results, correlated with corrosion data from previous work, indicate that grain refinement, incremental fraction of HAGBs and compressive residual stresses have positive effects on corrosion resistance and stress corrosion cracking (SCC) behavior, whereas a negative contribution comes from texture evolution. In particular, corrosion resistance and SCC decrease with the fraction of grains with the [0002] orientation present on the surface of the samples. The best trade-off is achieved after the first ECAP pass that guarantees an optimal combination of mechanical and corrosion behavior. In this condition the AZ31 alloy has better performances than the ones obtained through other approaches and is very promising for biomedical applications.</p></div>","PeriodicalId":645,"journal":{"name":"Journal of Materials Science","volume":"60 1","pages":"495 - 518"},"PeriodicalIF":3.5,"publicationDate":"2024-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142939315","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}
