Description

Catalytic properties of materials on the base of carbon nanotubes (CNT) modified by iron nanoparticles are studied. Iron nanoparticles have been prepared by radiation-chemical and chemical synthesis in reverse-micellar solutions. It is shown, that the large part of Fe nanoparticles obtained by methods considered adsorbed immediately on the CNT surface. Intensity change of optical absorption spectra of Fe nanoparticles in reverse-micellar solutions depending on contact time with CNT surface is studied. Using the method cyclic voltammetry comparison of catalytic activity of pure and modified CNT is carried out. It is found, that chemically prepared Fe nanoparticles have higher catalytic activity then radiation-chemically obtained ones

Abstract (Russian)

Изучены каталитические свойства материалов на основе углеродных нанотрубок (УНТ), модифицированных наночастицами железа. Наночастицы железа получены радиационно-химическим и химическим синтезом в обратномицеллярных растворах. Показано, что большая часть наночастиц Fe, полученных рассмотренными методами, мгновенно адсорбируется на поверхности УНТ. Изучено изменение интенсивности спектров оптического поглощения наночастиц Fe в обратномицеллярных растворах в зависимости от времени контакта с поверхностью УНТ. Методом циклической вольтамперометрии проведено сравнение электрокаталитической активности чистых и модифицированных УНТ. Обнаружено, что наночастицы Fe, полученные химическим методом, обладают большей каталитической активностью, чем наночастицы, полученные радиационно-химическим методом
