“…In comparison, the coercivity observed by Yi et al for Co 3 Sn 2 nanoparticles was only 131.5 Oe . Pereira and co‐workers also reported much lower coercivity values, but the films were far less crystalline than the films shown here and consisted of multiple Co–Sn phases . The coercivity value reported for an ALD Co film was 230 Oe .…”

Co–Sn and Ni–Sn with varying stoichiometry, including the intermetallic Co 3 Sn 2 and Ni 3 Sn 2 phases, have generally been prepared by, for example, ball milling, melting, different solution‐based techniques, solvo‐ and hydrothermal routes, electrodeposition, sputtering, and electron beam evaporation .

crystal structures of the participating metal components. An intermetallic compound is formed when the bonds between the dissimilar atoms are stronger than the bonds between the atoms of the same element.Because of their specific structure, intermetallic compounds usually exhibit unique physical and chemical properties that are potentially superior to their disordered alloy analogues and the pure metals. Such properties include, for example, magnetoresistance, [3,4] superconductivity, [5][6][7] enhanced catalytic activity, [8,9] and hydrogen storage capability. [10] Intermetallics and alloys containing Co or Ni and Sn with varying stoichiometry have mostly been studied as anode materials for Li-and Na-ion batteries. [11][12][13][14][15][16][17][18][19] As ferromagnetic materials, they also show potential for magnetic devices. [20][21][22] Furthermore, intermetallic Co-Sn and Ni-Sn compounds have also been studied for catalytic purposes. [23][24][25][26] For future applications like nanoelectronic devices, it is pivotal to be able to control the thickness and composition of thin films with sub-nanometer accuracy. Atomic layer deposition (ALD) is a thin film preparation method based on repeated, saturative, and irreversible surface reactions between alternately supplied gaseous precursors ensuring self-limiting growth of the desired material. [27,28] Owing to the self-limiting growth mechanism, ALD can be used to deposit uniform thin films over complex structures in a controlled and reproducible manner. No previous reports on the ALD of intermetallic Co 3 Sn 2 or Ni 3 Sn 2 thin films are found in the literature, and the ALD of other intermetallic compounds has also been scarce if existent at all. Intermetallic phases in Pt-In, [29] Pt-Sn, [30] and Ni-Fe [31] systems have been obtained by the postdeposition reduction of the corresponding ALD oxides. There are also some ALD studies on metal alloys, such as Pt-Ir, [32] Pd-Pt, [33][34][35] Ru-Pt, [36] Ru-Co, [37] Co-W, [38,39] Co-Pt, [40] Ru-Mn, [41] and Cu-Mn, [42] but no reports exist on materials exhibiting a specific intermetallic structure. Co-Sn and Ni-Sn with varying stoichiometry, including the intermetallic Co 3 Sn 2 and Ni 3 Sn 2 phases, have generally been prepared by, for example, ball Intermetallics form a versatile group of materials that possess unique properties ranging from superconductivity to giant magnetoresistance. The intermetallic Co-Sn and Ni-Sn compounds are promising materials for magnetic applications as well as for anodes in lithium-and sodium-ion batteries. Herein, a method is presented for the preparation of Co 3 Sn 2 and Ni 3 Sn 2 thin films using diamine adducts of cobalt(II) and nickel(II) chlorides, CoCl 2 (TMEDA) and NiCl 2 (TMPDA) (TMEDA = N,N,N′,N′tetramethylethylenediamine, TMPDA = N,N,N′,N′-tetramethyl-1,3propanediamine) combined with tributyltin hydride. The films are grown by atomic layer deposition (ALD), a technique that enables conformal film deposition with sub-nanometer thickness control. The Co 3 Sn 2 process fulfills the ...

“…To solve the abovementioned issues, the Co–Sn alloy is proposed as a new generation of light-absorbing material for solar-driven water evaporation. Co–Sn alloys are commonly used for electroplating and electrode materials, but their application as light-absorbing materials has rarely been explored. , To the best of our knowledge, the Co–Sn alloy was employed for water evaporation for the first time. Compared with other reported light-absorbing materials, the Co–Sn alloy has the following advantages and novelty: (i) low cost, (ii) wide and high optical absorption band, (iii) low scattering, and (iv) strong acid/alkaline resistance properties.…”

Solar-driven water evaporation is a promising solution to water pollution, the energy crisis, and water shortages. However, the approach in which the photothermal film is in direct contact with bulk water for water evaporation may lead to a large amount of heat loss, thereby reducing the light-to-heat conversion efficiency (η) of the photothermal film. Here, a highly efficient solar-driven water evaporation system was developed using a Co–Sn alloy-deposited Teflon (PTFE) film (Co–Sn alloy@PTFE) and super-absorbent polymers (SAPs) supported with a floating foam substrate. The Co–Sn alloy with full-spectrum (200–2500 nm) absorption characteristics is devoted to high light-to-heat conversion, while the porous PTFE with high mechanical performance can support the Co–Sn alloy. We used density functional theory to prove that the Co–Sn alloy had a strong adhesive force with PTFE without surfactants due to the high adsorption energy between the (101) crystal plane of the Co–Sn alloy and the hydroxyl group on the PTFE film. Importantly, via the SAP-based “water pump” design, we improved the η of the Co–Sn alloy@PTFE film to 89%, mainly because the SAP not only effectively performed water transportation but also markedly reduced the heat loss of the Co–Sn alloy@PTFE film. Our work highlights the strong potential of Co–Sn alloy@PTFE-based light-to-heat conversion systems for realizing highly effective solar energy-driven water evaporation.

Co can form a series of intermetallic compounds with Sn which usually exhibit unique physical and chemical properties. However, it is a challenge to control the phase composition of Co-Sn alloys. Here, we attempted to prepare Co3Sn2, CoSn and CoSn2 from the mixture of Co3O4/SnO2 using electro-deoxidation. We investigated the effects of sintering temperature for the mixed oxide plate and electrolysis conditions, such as voltage, electrolysis time, and molten salt temperature on the electro-deoxidation process of Co3O4/SnO2. The electrochemical deoxidation mechanisms of Co3O4, SnO2, and Co3O4/SnO2 composites were also explored by cyclic voltammetry using metallic cavity electrode. The Co-Sn alloys with different phase compositions, such as Co3Sn2, CoSn, and CoSn2, were obtained through controlling the molar ratio between Co and Sn in the initial Co3O4/SnO2 plate and the molten salt temperature. The obtained Co-Sn alloys were used as anode materials for lithium-ion batteries which showed 123.0, 246.5, and 323.4 mAh g−1 for Co3Sn2, CoSn, and CoSn2, respectively.
