“…Besides, Ga-related diffraction peaks have not be observed. Similar phenomenon is common in previous studies of Al-Ga-based alloys, and it has been confirmed that Ga exists as a form of Al (Ga) solid solution [30][31][32]. Yet, due to a low doping amount of Ga in the raw materials and the close atomic radius of the two atoms, the positions of Al diffraction peaks have not changed significantly.…”

For the purpose of investigating the effect of Zn replacement of In3Sn on the hydrogen production performance of Al-rich alloy ingots, Al-Ga-In3Sn alloys with various Zn dosages (0–5 wt.%) were prepared by a traditional melting and casting technique. The phase compositions and microstructures were characterized using X-ray diffractometer (XRD) and scanning electron microscope (SEM) with an Energy Dispersed X-ray system (EDS). The SEM results indicate that, with a small amount of Zn instead of In3Sn, the number and total area of grain boundary (GB) phases will decrease gradually, and the average single GB area will eventually stabilize. The distribution of Zn in the alloy is similar to that of Ga, and an area with high Zn content appeared in the high-Zn-doped sample. The melting behaviors of Al with other metals were measured by DSC. The reaction of these alloys and water were investigated at different temperatures. Compared with Al-Ga-In3Sn alloy, low addition of Zn changed the composition of GB phase and increased the maximum hydrogen production rate. The reason for the changes in the hydrolysis reaction of Al with the addition of Zn was discussed.

“…In addition to the Al and In 3 Sn phases determined by XRD testing, the existence of Ga as a solid solution of Al (Ga) has also been verified in many studies [30][31][32]. The EDX analysis shows that Zn exists in both the G and GB phases.…”

“…Only the diffraction peaks around 2θ = 38.2°, 44.3°, and 64.9° of Al are observed. The diffraction peaks uniformly shift to the left due to the radius of the Al atom is smaller than that of the Ga atoms . When the solid solution forms, the diffraction peaks of Al shift to left due to the crystal volume expansion originating from the formation of solid solution by Ga and Al.…”

Al2Ga)-xIn (x = 0, 2, 4, 6, 8 wt%) ternary aluminum (Al) alloys with different weight ratio of In for hydrolysis H 2 generation were prepared by meltingcasting technique. The phase compositions and microstructures of Al-rich alloys were investigated by X-ray diffraction (XRD) and high resolution scanning electron microscope (HR-SEM) equipped with an energy dispersive spectrometer (EDS). The effect of In addition ratio on microstructures and H 2 generation performance were investigated, and the hydrolysis mechanism for Al-Ga-In ternary Al-based alloys has been proposed. Al phase as matrix phase in the Al-Ga-In ternary alloy mainly determines the hydrolysis behavior, and the second phase In strongly promotes the hydrolysis process. The increase of In content can accelerate the H 2 generation rate as well as the final capacity and generation yield in neutral water. The generation yields for (Al2Ga)-x In (x = 2, 4, 6, 8 wt%) alloys at 50°C are 0.56, 0.59, 0.62, and 0.66, respectively. The raising hydrolysis temperature can elevate the initial hydrolysis rate, final H 2 generation capacity, and yield. The H 2 generation capacities of (Al2Ga)-8In alloy at 50°C, 60°C, and 70°C are 262, 290, and 779 mL·g −1 , respectively.

Application of Manganese-Based Materials in Aqueous Rechargeable Zinc-Ion Batteries

In recent years, aqueous rechargeable zinc-ion batteries (AZIBs) have attracted more and more attention not only because they use earth-abundant metals but also due to their improved safety and high volumetric energy density. As one type of promising electrode material for AZIBs, manganese-based materials are receiving considerable attention owing to their high theoretical specific capacity, non-toxicity, and low cost. This mini review summarizes the recent advances on the application of manganesebased materials (manganese oxide, manganate, and their composites) in AZIBs. In addition, the methods to enhance their zinc-ion storage properties are summarized and discussed, such as morphology engineering, doping, as well as compositing with other materials. Ultimately, some personal prospects for future research of the manganese-based materials for AZIBs are also proposed.
