Abstract
The threat of using сhemical warfare agents based on chlorine and its derivatives forces the creation of compact analyzers of these gases. As an example of a compact analyzer, there can be elements of visual analysis of chlorine on the glass of a car or a gas mask. One of the promising materials for the visual analysis of chlorine and its derivatives is thin films of nickel hydroxide. A simple method of electrochemical production allows the controlled deposition of Ni(OH)2 on a glass base with a conductive layer of SnO2. Ni(OH)2 films have been obtained by cathodic deposition from 1 M Ni(NO3)2 on a glass with a current-conducting SnO2 layer. The films have a porous structure and consist of chaotically joined formations of 100–150 nm in size. Nickel hydroxide films were obtained by cathodic deposition in a double–electrode mode (direct current with a density of 0.4 mA / cm2) in a 1M nickel nitrate solution by the reduction of nitrate ions by the reactions:
