Детально исследовано влияние концентрации серы на композиционные, морфологические, оптические и структурные свойства наночастиц NiS. Рентгеновская дифрактограмма подтверждает образование наночастиц NiS без каких-либо примесей. Спектры комбинационного рассеяния света показывают наличие активных мод NiS в синтезированном материале, полученном при различной концентрации серы. Электрохимические характеристики синтезированного порошка NiS оценены методами циклической вольтамперометрии, гальваностатического заряда-разряда и электрохимической импедансной спектроскопии в электролите КОН. Удельная емкость порошкового электрода NiS была измерена трехэлектродным методом и подтверждает максимальное значение 315.8 Ф/г при скорости сканирования 5 мВ∙с-1. Расчетное значение плотности энергии и плотности мощности порошкового электрода NiS составляет 3.324 Вт∙ч∙кг-1 и 199 Вт∙кг-1 соответственно при меньшей плотности тока. Настоящее исследование предлагает простой и недорогой метод – МГИ, позволяющий контролировать структурные, оптические и морфологические свойства сульфида никеля, и который имеет большой потенциал для синтеза сульфидов других металлов.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>сульфид никеля</kwd><kwd>наночастицы</kwd><kwd>наноструктуры</kwd><kwd>электрохимические измерения</kwd><kwd>суперконденсатор</kwd><kwd>метод горячей инъекции</kwd></kwd-group><kwd-group xml:lang="en"><kwd>nickel sulfide</kwd><kwd>nanoparticles</kwd><kwd>nanostructures</kwd><kwd>electrochemical measurements</kwd><kwd>supercapacitor</kwd><kwd>hot injection method</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Wang G., Zhang L., Zhang J.
