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.

Low‐density magnesium (Mg) alloys are excellent engineering materials, and can significantly reduce energy consumption by replacing existing steel and aluminum materials. However, Mg species are susceptible to corrosion, especially in harsh environments (high‐temperature or acidic), severely limiting the range of practical applications. Here, 2D covalent organic framework (COF) is synthesized with pore diameters ranging from 1.5 to 2.9 nm to obtain ultrafast nanofluidic channels. Loaded with silver (Ag+) ions, 2‐mercaptobenzimidazole (2‐MB) inhibitors are immobilized in the COF channels through the silver bridges. Based on the strong metal‐complexing capability, Ag+ ions precipitated with various corrosive media (Cl−, Br−, I−, SO32−, S2−, S2O32− SO42−, CO32−, PO43−); meanwhile, the 2‐MB inhibitors are rapidly released through the nanofluidic channels, forming a passivation film as a corrosion barrier to protect the Mg substrate. After integration with commercial polyethersulfone (PES), the COF‐based coating exhibits high repairing capability achieving 100% damage restoration within 7 h, outperforming all existing coatings of Mg alloys. Notably, the coating shows almost complete protection of Mg alloys after being treated in respective 473 K, acidic (pH ≈4.0), and alkaline (pH ≈10.0) environments.
