研究了超高浓度氯化锂盐包水电解液中铝-铁合金的电沉积。不同的技术，包括循环伏安法，计时电流法，X-射线荧光，扫描电子显微镜，X-射线衍射，并在低温下的电测量被用来表征合金电化学系统和沉积的薄膜。观察到铁对碳纳米管沉积的催化作用，其中碳纳米管的沉积速率在铁的存在下显著增加。合金元素铁显著抑制了沉积态非晶薄膜的再结晶。同时，它也大大抑制了超导体的超导电性。(c)2022 Elsevier B.V.保留所有权利。
Electrochemical deposition of rhenium-iron alloy from water-in-salt electrolytes containing a super-high concentration of lithium chloride is investigated. Different techniques, including cyclic voltammetry, chronoamperometry, X-ray fluorescence, scanning electron microscope, X-Ray diffraction, and electrical measurements at cryogenic temperature are used to characterize the alloy electrochemical system and the deposited films. The catalytic effect of iron on rhenium deposition is observed, where the deposition rate of rhenium significantly increases in the presence of iron. Alloying rhenium with iron significantly inhibits the recrystallization of the as-deposited amorphous films. At the same time, it also greatly suppresses the superconductivity of rhenium.(c) 2022 Elsevier B.V. All rights reserved.
