“…3d) confirms the structure of Fe3O4. These results differ from the previously reported, where structure of Al2O3 was observed after leaching with NaOH [17], while the Fe3O4 spinel was found to form after leaching and calcinations [15]. In the initial experiments the Al65Cu20Fe15 catalyst was used as received (in the form of thin flakes).…”

The Al65Cu20Fe15 (in at.%) rapidly solidified ribbon in the form of brittle flakes was produced by melt-spinning technique. It consists the cell or dendrites of the icosahedral quasicrystalline I-phase surrounded by copper rich cubic τ-Al(Cu, Fe). The pulverized ribbon (fraction <32 μm) was subjected to NaBH4 or 20% aqueous NaOH treatment, which led to the formation of oxide in the form of thin flakes at the outer layer of the powder particles. Test of the catalytic properties of the as spun ribbon and powder before and after treatment was made in the reaction of phenylacetylene hydrogenation. It was shown that for as received ribbon, even at very mild conditions (60 °C, H2 pressure of 5 bar), 40% of phenylacetylene was converted to hydrogenation products with 0.7 styrene/ethylbenzene ratio. The use of pulverized ribbon resulted in improvement of activity, with the same ratio of reaction products. The effect of treatment with NaBH4 led to improvement of the catalyst activity, while strongly alkaline solution of NaOH worsened significantly the catalytic activity, but improved selectivity to styrene (styrene/ethylbenzene=1.2).

“…Fu et al [59] conducted a study showcasing the effective adsorption of both CO and water through Cu doping of the Fe3O4 (111) surface, which in turn facilitated the steam reforming process. Furthermore, recent advancements highlighted the remarkable enhancement in the specific surface area achieved by the 2D Cu-Fe-Al-O nanosheet structure, leading to the creation of additional active sites for metallic Cu [60] . This innovative structure not only contributed to the stability of the catalyst but also enhanced its catalytic activity, showcasing the potential of Cu-Fe composite materials [61] .…”

The main deliberation of this review paper is on metallic catalysts, including Cu-based catalysts, with distinct formulations and compositions, utilized for steam reforming of methanol (SRM). The review critically examines the performance of these catalysts, considering the active components, supports, promoters, and their interactions. Additionally, the review identifies and elucidates the various kinds of reaction mechanisms and routes involved in SRM. This comprehensive analysis provides valuable insights into the progress of well-organized and effective catalysts for SRM. To achieve high yields of H2, it is crucial to conduct a fundamental study of the role of copper as a component in both mono and multimetallic systems, as well as the nature of support. These factors are essential to understand the catalytic mechanisms involved in the steam reforming of methanol and to develop effective strategies for optimizing hydrogen production. Therefore, a thorough investigation of copper-based catalysts and their interaction with the support material is essential for the development of highly efficient steam reforming processes.

“…Dealloying is a preparation method that can selectively remove one or several components in the alloy so that the remaining elements spontaneously evolve into micro/nano structures . With the characteristics of low cost, simple operation, and controllable morphology, it is widely used in the fields of energy storage, catalysis, water decomposition, biomaterials, and so on. The parameters in dealloying can control the final morphology of dealloyed materials.…”

High-entropy oxides (HEOs) are materials with a multielement mixture and a stable structure, which are widely used in energy storage due to their electrochemical properties. For application to supercapacitors, the method of preparation of HEOs needs to be improved, and the energy storage mechanism of the material needs to be investigated. In this experiment, 3 M NaOH was used to etch the FeCoNiCrMnAl95 alloy, and then (FeCoNiCrMn)3O4 was successfully produced by a facile oxidation treatment. HRTEM images show that the materials have a porous structure, and EDS mapping suggests that the individual elements are evenly distributed. The XRD and SAED patterns indicate that it has a stable crystal structure. The HEOs prepared by dealloying exhibited excellent supercapacitor characteristics, with a specific capacitance of 639 F/g at 1 A/g and retention of 80.77% at 10 A/g. Density functional theory (DFT) simulations back up this excellent energy storage capability. This work offers a novel method for manufacturing HEOs and a solid option for supercapacitor anode materials.
