Abstract

The process of electrodeposition of nickel–titanium dioxide composite coatings from an electrolyte based on a choline-containing ionic liquid was studied. To increase the content of the dispersed phase in the composite, it is appropriate to add water to the electrolyte. With inclusion of the titanium dioxide particles into a nickel matrix, the microhardness of the coating increases. The obtained coatings show electrocatalytic activity in the reactions of hydrogen and oxygen evolution in an alkaline aqueous solution, which can be used in electrolytic decomposition of water.

基于含胆碱离子液体的电解质沉积Ni-TiO 2功能复合涂层

摘要

研究了基于含胆碱离子液体的电解质对镍-二氧化钛复合涂层的电沉积过程。为了增加复合物中分散相的含量，将水添加到电解质中是合适的。通过将二氧化钛颗粒包含在镍基体中，涂层的显微硬度得以提高。所获得的涂层在碱性水溶液中在氢气和氧气释放的反应中显示出电催化活性，可用于水的电解分解。
