    Description / Table of Contents: Abstract Методом рентгеноэлектронной спектроскопии исследованы валентные состояния молибдена в нанесенных на γ-Al2O3 окисномолибденовых катализаторах. Установлено, что в процессе приготовления катализатора при 1000°C окись молибдена взаимодействует с окисью алюминия. В свежеприготовленном катализаторе молибден находится в основном в шестивалентном соотоянии. В восстановленном катализаторе присутствуюот Mo+6, Mo+5 и Mo+4. При окислении уменьшается концентрация Mo+5.
    Notes: Abstract The valence states of molybdenum in molybdenum oxide catalysts supported on γ-Al2O3 have been studied by the ESCA technique. Molybdenum oxide was found to interact with aluminium oxide in the course of catalyst preparation at 1000°C. In a freshly prepared catalyst molybdenum is present primarily in the hexavalent state. In the reduced catalyst Mo6+, Mo5+ and Mo4+ are present.

    Description / Table of Contents: Abstract Методом рентгеновской фотоэлектронной спектроскопии определено изменение относительного содержания оксидов железа (II), (III) и металлического железа в процессе восстановления жедезохромового катализатора в температурном интервале 100–500°C. Показано изменение состава поверхности катализатора в процессе восстановления.
    Notes: Abstract X-ray photoelectron spectroscopic studies of the reduction of iron-chromium catalysts have been carried out to determine changes in the relative surface concentrations of iron(II) and (III) oxides and metallic iron and in its surface composition at 100–500°C.
