In this work, we successfully transformed Ni, Co, Mn, and Al in spent LIBs into novel catalysts (i.e., NixFeyCoMnAl) for hydrogen generation from hydrazine hydrate (N2H4·H2O), while recovering the Li as lithium phosphate to prepare new LIBs. The synthesized nickel-based catalysts were characterized by X-ray diffraction, electron microscopy techniques, and X-ray photoelectron spectroscopy, and the effects of Al, Co, and Mn in the cathode materials of spent LIBs on the hydrogen (H2) production performance of the obtained NixFeyCoMnAl catalyst were investigated. The metallic Al in the catalyst enhanced the H2 selectivity and the turnover frequency (TOF) in N2H4·H2O decomposition, whereas Co had a minimal effect on the H2 selectivity and TOF, and Mn increased the TOF without significantly affecting the H2 selectivity. Furthermore, the influences of temperature and the NaOH and N2H4·H2O concentrations on N2H4·H2O decomposition were investigated to evaluate the performance of the Ni1Fe3CoMnAl catalyst. When N2H4·H2O was completely decomposed, the optimal H2 selectivity and TOF reached 91.67% and 38.56 h−1, respectively.

Generally, an important property for use in such cyclic applications is a small hysteresis, which is linked to functional fatigue resistance. Leveraging microstructural features which promote martensite nucleation is one strategy to achieve reduced hysteresis. In the austenite phase of NiTi, the Σ9(114)[110] symmetric tilt grain boundary has been recognized as one such feature. We have performed a series of molecular dynamics simulations to characterize this grain boundary and its relationship to the martensitic transformation. Upon thermal equilibration, even above the transformation temperature, the grain boundary spontaneously forms a twinned martensite structure at its core, which serves as a nucleus during the martensitic transformation. When the grain boundaries are near one another, the energetic barrier to the transformation is reduced and a small hysteresis results. In polycrystalline microstructures, the added constraints lead to an expanded transformation window and retained austenite upon cooling. Based on these results, grain boundary engineering could be an effective strategy to produce shape memory alloys with improved performance in cyclic applications.</div>","PeriodicalId":605,"journal":{"name":"JOM","volume":"77 5","pages":"2844 - 2851"},"PeriodicalIF":2.1,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143835597","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work aims to study the effect of substrate temperature (Ts) on the optical parameters of fluorine-doped tin oxide (FTO) thin films, where polycrystalline FTO thin films were fabricated by spray pyrolysis method on glass substrates at different substrate temperatures (Ts = 360–480)°C.

Transmittance of the films was recorded at room temperature using ultraviolet–visible (UV–vis) spectroscopy in the wavelength range of 290–1100 nm. Transmittance was used to deduce the absorption coefficient, direct bandgap energy, extinction coefficient, Urbach tail, and reflectance. Then, reflectance was used to calculate the refractive index, real and imaginary parts of the complex dielectric constant, and energy loss. The dependence of these optical parameters on the substrate temperature was investigated.
